Santa, forget the socks and ties this year. I need horsepower under the tree. Santa, bring me tools. I’ve got work to do. This wind’s waiting on my stand, and I need some help from you.

A torque wrench for the heads, a home to clean the board, and a breaker bar so I don’t throw my shoulder out no more. Oh, Santa, bring me tools and parts, a camshaft with a low B, some sturdy springs and headers built to make it rain.

Oh, it’s going to be a Bullnose Christmas. The B-no stands ready, the six still pulls its weight, but there’s a wind on the way to make next Christmas great.

I need a ring compressor, plastic gauge from your sack, and if there’s room, a trimming tool. I promise, Chris, I’ll pay you back.

Oh, Santa, bring me tools and parts, a timing chain, some plugs, that SPK, and it didn’t take man A-F. That sing some rockers, rid and molar. Oh, it’s going to be a Bullnose Christmas.

Here’s the deal, Santa. Next Christmas, I’ll hook up the Bullnose to your sleigh and let Rudolph take the night off. No reindeer can match a Ford Windsor in full stride.

Oh, pack your bag tight. My V8 roars into the night. A bench seat where my kids can play. Next year, we’ll cruise on Christmas Day.

Oh, it’s all going to be a Bullnose Christmas. Thanks, Santa. Cookies and milk are by the tree, and if you’ve got a spare set of valve covers, I wouldn’t complain. Merry Christmas from Bullnose Garage.

Hi folks, Ed here. Welcome back to Bullnose Garage. Imagine an axle tough enough for rugged off-road action but light enough for everyday driving. One that is so versatile and reliable you’ll find it in front and rear setups alike, from trucks to sports cars, in both solid and independent configurations. It’s been around for over 70 years and still ranks among the top choices in the 4×4 world. Meet the Dana 44.

The Dana 44 isn’t just another axle; it’s a proven performer found in everything from classic Broncos to Jeep CJs and more. If you’re into Bullnose Fords, any classic trucks, or off-roading in general, chances are this axle rings a bell. If not, stick around because we’re covering everything you need to know. Even if you know this axle, there’s a good chance you’ll pick up something new. I’ll also clear up the differences between the solid and independent suspension versions, as well as the front and rear axle setups. There is a lot to cover, so get comfortable.

Hello! To start, let’s clarify the Dana 44 family tree. The Dana 44 name actually covers a whole series of axles by the Dana Corporation, dating back to the 1940s. It includes a solid front axle with an offset diff for 4×4 work, a solid rear axle with a center diff, and an independent front suspension using Ford’s twin traction beam setup. This axle has been a top choice for off-roaders and classic truck owners for decades because it’s tough, adaptable, and this is important, easier to work on than most.

The beauty of the Dana 44 is its adaptability across all kinds of vehicles. You’ll find it in both front and rear setups in everything from Ford trucks to Jeep CJs, some military vehicles, and high-performance cars with an independent suspension setup. We’re about to take a closer look at both the solid axle and twin traction beam, or TTB, versions, along with how each was used, especially in Ford’s lineup. For those of you looking to source parts to find a solid donor axle, I’ll share some charts later in the video showing which models and years came with the Dana 44.

First up, we’ll check out the solid axle version. Let’s start with what makes a solid Dana 44 such a popular choice. For one, this axle was commonly paired with leaf springs in Ford’s heavier duty setups, and it often uses a high pinion design. Now, when I say high pinion, it means the pinion gear sits higher up in the axle housing than in the standard setup. This design offers a few advantages, especially for off-roading. First, it improves ground clearance, lifting the drive shaft angle to keep it safely clear of rocks, logs, and other tall obstacles. On top of that, this high pinion setup uses reverse cut gears, which provide extra strength in the forward direction. That makes it ideal for front axles where the torque is applied as you pull the vehicle forward. With a high pinion Dana 44, you get added strength, improved clearance, and a smoother drive shaft angle, especially helpful if your truck is lifted.

The solid D44 is designed to handle a wide range of vehicle setups. It functions well as either a front or rear axle, giving it flexibility across different builds. In classic Fords, it’s typically found up front, but in duty setups, you’ll also see it used in the rear. Now, as a rear axle, it’s not quite as beefy as a Dana 60 or a Ford 9-inch, but it’s a solid choice and comparable to the 8.8 when you’re looking to keep weight down and agility up without compromising strength.

Now, Ford isn’t the only one to use the Dana 44. Its versatility attracted other manufacturers like Chevrolet, Dodge, Jeep, International, and even some imports, making it one of the most widely used axles around. If you’re curious about the range of models that came factory-equipped with the 44, here’s a chart with all the details. This is a great reference if you’re thinking of sourcing parts or finding a donor vehicle.

So, let’s talk specs. The solid Dana 44 typically comes with a 30 spline axle, striking a good middle ground for strength and flexibility. Earlier versions sometimes had 19 or 27 splines, but the 30 spline is by far the most common for moderate duty work. If you’re planning to go further off-road, then there are aftermarket options with 33 or even 35 splines. Just remember, if you go up in the spline count, you’ll likely need a compatible differential carrier to handle those shafts. The D44 has an 8 and 1/2 inch ring gear. Now, it’s not as large as what you’ll find in the 9-inch or the Dana 60, but it’s plenty strong for moderate off-roading and light towing.

The Dana 44’s gear ratios are also flexible, ranging from 3.07 to 1 to 4.56 to 1. Lower ratios like 4.10 and 4.56 are great for torque-heavy applications, while higher ratios like 3.55 are more fuel efficient for highway driving. The Dana 44 uses a carrier break around the 3.73 mark, so if you’re planning to switch from a high to a low ratio, you’ll need to change out the carrier. The gross axle weight rating for the Dana 44 ranges from 3,500 to 3,800 pounds, depending on the setup. While it doesn’t match the brute strength of the Dana 60, the 44 is more than capable for medium duty tasks in a 4×4 setup.

The solid Dana 44 axle typically measures about 65 to 68 inches wide from flange to flange, with axle tubes between 2.75 and 3 inches in diameter. This width provides a good balance, keeping the front end light for off-road use without compromising durability. The solid Dana 44 axle itself weighs in around 250 to 300 pounds, making it significantly lighter than the Dana 60. Most Boss AER trucks came equipped with ball joint knuckles on the Dana 44. Ball joints are easy to maintain and offer more precise steering, making them a solid choice for most setups. Some older versions feature kingpin knuckles for added durability, which off-roaders still appreciate.

Further strengths last here a quick note on fluid. The Dana 44 holds around 2 to 3 quarts of gear oil. Maintaining the oil level is crucial, especially for heavy off-roading, as it prevents the gears and bearings from overheating and wearing prematurely. If you’re looking to beef up your solid Dana 44, a whole range of upgrades can take it from a decent axle to a serious off-road contender. Stock shafts work okay for light to moderate off-roading, but if you’re planning to push further, chromoly shafts are a great upgrade. You can also go for a thicker spline count like 33 or even 35 splines if you’re aiming for that maximum strength. But like I said, keep in mind that a higher spline count often requires a compatible carrier, so plan accordingly.

If you’re going to head that route, a locker upgrade makes a big difference in off-road traction. Several types of lockers are available, but selectable lockers like those from ARB are popular because you can engage them only when needed. Keep in mind that adding a locker increases stress on the axle shafts and U-joint, so upgrading your shafts is a smart move here. If you’ve got manual locking hubs, upgrading to a heavy-duty set like Warn hubs makes for a worthwhile investment. Manual hubs are typically stronger than automatic ones, which matters if you’re running larger tires or adding extra load to the front end.

If you’re planning to take your truck over rougher trails, consider adding a truss or skid plate. A truss runs along the top of the axle, adding reinforcement to keep it from flexing under heavy use, and skid plates or reinforced diff covers give you a little bit of extra protection against rocks or trail debris.

And finally, let’s talk about ball joints and knuckles. Most Bullnose trucks with the Dana 44 come with ball joints, which work just fine for most setups. But if you’re planning on larger tires or adding weight to the front end, like a winch bumper, upgrading to a heavy-duty ball joint or even reinforced knuckle is worth considering. This upgrade adds durability and keeps your steering nice and precise.

So let’s switch gears to the twin traction beam, or TTB, Dana 44. It’s a unique setup introduced back in 1980. This version is entirely different from the solid axle, featuring an independent front suspension design rather than one continuous housing. TTB has two beams that pivot independently from a central point. This design aimed to give trucks a smoother, more car-like ride on pavement without sacrificing off-road capability. Ford primarily used the TTB Dana 44 in the F-150 and Bronco models. If you’re wondering which models came with the D44 TTB axle, here’s a quick reference chart. This should be especially useful if you’re seeking TTB-specific parts or looking for a donor vehicle.

Ford designed this axle for folks who wanted a truck that can handle trails while still running comfortably on the highway. While it’s not as rugged as the solid axle version, it offers a strong balance between off-road capability and on-road comfort, making it popular in lighter duty trucks. However, for serious off-roading, the TTB setup has its limitations. Its independent beams and pivot points wear faster under heavy use, and lifting the TTB can create challenging geometry issues.

The TTB Dana 44 usually comes with coil springs instead of leaf springs, which helps create that smoother ride. With two pivot points, one at each beam, it requires regular maintenance, especially for frequent off-road use. These beams are typically made from stamped steel, which is lighter but less durable than a solid axle under extreme off-road conditions. Like its solid axle brother, the TTB Dana 44 uses 30 spline shafts. However, since it’s not a single housing, each side includes a half shaft with U-joints that allow each beam to flex independently.

The TTB Dana 44 generally offers similar gear ratios to the solid axle, ranging from 3.07 to 1 to 4.56 to 1, so you can choose based on whether you need torque for off-road or a higher ratio for on-road fuel efficiency. Lifting a TTB axle is trickier, as the geometry can get thrown off even by modest lifts. This is one reason why some hardcore off-roaders eventually swap the TTB for a solid axle. The TTB’s main strength is ride comfort; its lighter front end provides a smoother ride on pavement, and a big advantage if your truck spends a lot of time on the road.

The TTB Dana 44 can be upgraded as well, although it has a unique set of options because of its independent design. First up, the heavy-duty U-joints and half shafts. Because the TTB relies on half shafts and U-joints for independent movement, a common upgrade here is stronger U-joints and heavy-duty half shafts. Stock parts work well under moderate use, but if you’re heading off-road with larger tires or more power, upgrading these components can prevent early wear or breakage.

Another key upgrade is bushings and pivot brackets. The TTB has a lot of moving parts, and one area that sees a lot of wear is the pivot points. Swapping in polyurethane bushings instead of the stock rubber ones and adding reinforced pivot brackets can make a big difference in stability. This helps reduce play and keeps everything lined up nicely.

Another useful upgrade for TTB setups is adding a truss. Yep, you can add a truss to the TTB beams too. Say that five times fast! TTB beams truss kits strengthen the beams to prevent flexing under load, especially useful if you’re running larger tires or taking the truck off-road regularly. A lot of TTB owners also go for extended radius arms. Stock length arms can sometimes cause binding when the suspension cycles over bumps, but extended arms let the suspension move more freely. They improve the suspension geometry if you’re lifting the truck, helping with handling and stability on rough terrain.

And speaking of lifts, lifting a TTB requires drop brackets to keep the pivot angles correct. TTB lift kits often include these drop brackets along with coil spring spacers or new coil springs altogether to keep the height right. Drop brackets are crucial for maintaining proper geometry; without them, lifting a TTB can cause uneven joint wear and affect handling.

Last but not least, just like with a solid axle, adding a locker can be a great upgrade if you’re planning to take the TTB off-road. Just remember, the TTB’s design is a little more complicated than a solid axle, so lockers can add some extra strain to the system.

And that’s the Dana 44 family in a nutshell. If you’re looking at the solid axle for off-road durability or the TTB for a smooth ride, the Dana 44 has you covered either way. With the right upgrades, regular maintenance, and a bit of know-how, these axles are ready for just about anything, whether it’s the trail, highway, or somewhere in between.

So here’s a little fun fact and something you might not expect right here at the end of the video: The Dana 44 wasn’t just for trucks. Dana also created an independent rear suspension version specifically for sports cars. The IRS D44 maintained the axle strength while being compact enough for performance-focused cars. This version appeared in some legendary rides, including the Chevy Corvette C3 from 1980 to 1982 and the C4 manuals from ’85 to ’96, the Dodge Viper, and even classic Jaguars like the E-Type and XJ. It’s a testament to the versatility of the Dana 44 platform.

There you go, guys. That’s everything that I know, or pretend to know, about the Dana 44 series of axles by the Dana Corporation. Now, this can be a very confusing topic, especially for somebody who’s new to axles or new to working on vehicles, because all these different vehicles are called Dana 44. And unless you know what you’re looking for, it can be hard to find the right information. So just remember, you’ve got a Dana 44 front axle that’s solid, a Dana 44 front axle that’s independent, and a Dana 44 rear axle, and they’re all different. On top of that, they came in all different kinds of vehicles: Fords and Dodges and Chevys, and we went over it, right? There’s a lot of different vehicles you can find them in.

So, hopefully this video gave you some good background information. It was just a real quick overview, but hopefully you learned something. If you did, guys, give me a like, give me a subscribe. I really appreciate that; it helps me out a lot. If you have any questions, comments, concerns, gripes, internet ramblings, if I got something wrong, drop me a comment and let me know.

Introduction

Hey folks, Ed here from Bullnose Garage. Today, we’re diving into a legendary piece of engineering that’s been holding up the off-road community for over 70 years—the Dana 44 axle. If you’ve ever wondered why this axle has become a staple in everything from classic trucks to sports cars, stick around. We’re breaking down the solid vs. Twin Traction Beam (TTB) setups, specs, and the best upgrades to make your rig trail-ready.

The Dana 44 Family Tree

First off, let’s clear up a common misconception: the Dana 44 isn’t a one-size-fits-all axle. It’s an entire series crafted by the Dana Corporation since the 1940s. Whether you’re talking about a solid front axle with an offset differential for 4×4 work or an independent front suspension using Ford’s TTB setup, you’re still talking Dana 44. Its adaptability has made it a go-to choice for rugged off-roaders and classic truck aficionados alike.

Solid vs. TTB: What’s the Difference?

Solid Axle

The solid Dana 44 is a popular choice for a reason. It’s often paired with leaf springs and features a high-pinion design. “High pinion” means the pinion gear sits higher in the axle housing, providing better ground clearance and a favorable drive shaft angle. This setup is particularly ideal for front axles, where you need that extra strength and clearance when pulling your vehicle forward.

Twin Traction Beam (TTB)

Ford introduced the TTB Dana 44 in 1980 as an independent front suspension option. It features two beams pivoting from a central point, designed to offer a smoother ride on pavement without sacrificing off-road capability. While not as rugged as its solid counterpart, it’s ideal for those looking for a balance between off-road capability and on-road comfort.

Specs and Configurations

The Dana 44 isn’t just flexible in its design; it’s also versatile in specs. Most solid Dana 44s come with a 30-spline axle, which is a good middle ground for strength. They can range in gear ratios from 3.07:1 to 4.56:1, allowing you to tailor your setup for torque-heavy off-roading or fuel-efficient highway driving.

Solid Axle Specs

  • Spline Count: Mostly 30, but options for 33 or 35 splines exist.
  • Ring Gear Size: 8.5 inches.
  • Width: Typically 65 to 68 inches flange to flange.
  • Weight: Around 250 to 300 pounds.

TTB Axle Specs

The TTB setup usually comes with coil springs, requiring regular maintenance due to its independent nature. It shares similar gear ratios with the solid axle but is generally lighter, making it more suited for on-road comfort.

Best Upgrades for Off-Road Performance

Thinking about beefing up your Dana 44? Here are some upgrades that can transform it from a decent axle into a serious off-road contender.

Solid Dana 44 Upgrades

  • Chromoly Shafts: Great for those planning more extreme off-roading.
  • Lockers: ARB selectable lockers are a popular choice.
  • Manual Locking Hubs: Opt for heavy-duty sets like Warn.
  • Truss or Skid Plates: Reinforce the axle to prevent flexing.

TTB Dana 44 Upgrades

  • Heavy-Duty U-Joints and Half Shafts: Essential for handling larger tires.
  • Polyurethane Bushings: Replace stock rubber to improve stability.
  • Truss Kits: Strengthen the beams to prevent flexing.
  • Extended Radius Arms: Improve suspension geometry.

Conclusion

Whether you’re eyeing the solid axle for its off-road durability or the TTB for a smoother ride, the Dana 44 has something for everyone. With the right upgrades and a bit of know-how, these axles can tackle just about anything you throw at them, from the trail to the highway.

Hi folks, Ed here. Welcome back to Bullnose Garage. What’s big, bad, and makes other V8s look like they skipped leg day? That’s right, it’s the Ford 460 big block. If brute force, jaw-dropping torque, and an engine that dominates on any road sounds good to you, buckle up. Today, we’re breaking down the legendary Ford 460. Whether it’s turning heads at a stoplight, hauling massive loads, tearing up the drag strip, or just cruising, this gas-powered behemoth can do it all.

Introduced in 1968, the 460 V8, aka the 7.5 L, has ruled streets, highways, and job sites for decades. Whether it was powering the iconic F-series trucks or hauling the Lincoln Continental’s massive luxury frame, the 460 earned its reputation for serious pulling power. Keep watching because we’re drilling down into everything you need to know, including the 460 specs, performance potential, and the killer mods that still make it a builder’s dream.

Now, while small blocks like the 302 or 351 Windsor love to rev high, the 460 plays a different game, delivering brute force where it counts: low-end torque. Forget high redlines; this beast is built to move trailers, boats, or whatever you hitch up to. Even though it retired in ’97, the 460 is still a go-to for modern builds, off-roading, drag racing, or swapping into a classic truck for some extra heft.

The 460 made its debut in 1968 as part of Ford’s 385 engine family alongside the 429 and 370. The name comes from the 3.85 in stroke, not because it was a 385 engine, which there isn’t. The 460 had a different role than its 429 sibling, which was more performance-oriented. Ford needed an engine that could provide massive low-end torque for their full-size trucks and larger vehicles. As a result, the 460 became a staple in Ford’s heavy-duty lineup, known for its ability to haul practically anything you could throw at it. It found its way into both trucks and luxury cars, starting with models like the Lincoln Continental and Ford Thunderbird.

The engine design made it ideal for towing and hauling while also delivering smooth power in those early ’70s land yachts. But as the ’70s rolled on, stricter emissions regulations started hitting the entire auto industry. Like most engines of the era, the 460 got hit hard. Compression ratios dropped, and so did horsepower, from around 365 to much lower numbers by the late ’70s. Even with the drop in horsepower, the 460 still packed enough torque to stay in demand, powering trucks, RVs, and motor homes well into the ’90s.

Here’s a quick look at the vehicles that rolled off the factory floor with the 460 under the hood. Towing a trailer or boat, the 460 won’t even flinch. That’s why you’ll still find these engines in old RVs and motor homes. They were built for the long haul, and decades later, they’re still cruising down highways on road trips.

Like many of Ford’s engines, from 1983 onward, Ford switched to a one-piece rear main seal, reducing oil leaks—an improvement over the early rear two-piece seal. This makes rebuilds easier and cleaner. In 1979, Ford changed the 460’s balance from internal to external, shifting some of the balancing work to the flywheel or flex plate and harmonic damper, which was a cost-saving measure. By the 1990s, Ford introduced EFI, or electronic fuel injection, enhancing throttle response and improving fuel control, especially on trucks and RVs. These changes made the later 460s more user-friendly for modern driving while maintaining their legendary torque output.

Let’s dig into the specs because the 460 brings some serious numbers to the table. The 460 lives up to its name with 460 cubic inches, or 7.5 L, of displacement. It’s got a 4.36 in bore and a 3.85 in stroke, both of which contribute to the low-end pulling power this engine is known for. Early 460s from ’68 to ’71 had a high 10.5 to 1 compression ratio, delivering around 365 horsepower and 485 lb-ft of torque. However, the ’70s brought new challenges; emissions regulations forced Ford to drop that to around 8.01, cutting back output to around 220 horses and 350 lb-ft torque today. Raising compression with new pistons or upgrading the cam is a common way to restore or increase performance. The height stayed consistent at 10.32 in throughout production.

In terms of dimensions, the 460 measures roughly 34 in long, 27 in wide, and about 30 in high. It’s a large displacement engine that fits well in trucks and large vehicles but might need some creative work to fit into smaller engine bays. As for weight, the 460 tips the scales at around 720 lbs with its cast iron block and heads. That’s part of what makes it so tough, but you’ll definitely want to consider that if you’re planning a swap into something small. The firing order follows the standard Ford V8 sequence: 1-5-4-2-6-3-7-8. As for oil capacity, the 460 holds about 6 quarts, filter included. If you’re running it hard or towing, consider upgrading to a larger oil pan for better cooling.

Now about the crankshaft. Factory 460s came with a cast iron crankshaft, which is plenty strong for most applications. But if you’re chasing high performance, upgrading to a Ford steel crank is the best move for peace of mind. The 460 is known for its sturdiness, and with the right upgrades, it’s capable of cranking out far more power than it had from the factory. Builders can push these engines into the 600 to 700 horsepower range fairly easily. Add forged internals, high flow heads, and a beefed-up valve train, and the 460 turns into a force to be reckoned with on the street or at the strip.

Even though the 460, 429, and 370 all came from Ford’s 385 engine family, each one was designed with a different purpose in mind. The 460 is designed to haul serious weight effortlessly. It has the longest stroke of the bunch at 3.85 in. Pair that with a big bore, and you’ve got an engine perfect for getting massive trucks and RVs up to speed without needing to rev too high. It was also used in those land yachts I mentioned, like the Lincoln Continental, where the only thing bigger than the engine was the back seat. The 429, on the other hand, is all about performance. It shares the same 4.36 in bore as the 460, but it has a shorter 3.59 in stroke, making it ideal for high-revving performance. This engine was perfect for muscle cars like the Mustang and Torino, where top-end horsepower mattered most. The Cobra Jet and Boss 429 became legends for a reason, built to wind up quicker and push harder at higher RPMs. If you’re chasing speed and high RPM thrills, the 429’s shorter stroke is your ticket.

Then there’s the 370, the all-reliable of the family, with a smaller 4.05 in bore and the same 3.59 in stroke as the 429. The 370 wasn’t built for speed or heavy pulling; instead, it was designed to handle the grunt work in medium-duty trucks and industrial applications. The 370 is the engine you’d find in a vehicle that needs to keep running day in and day out. It’s not about speed or flash; it’s about showing up every single day.

Here’s a fun fact and a useful tip for engine builders: the 429 and 460 blocks are basically identical. The real difference comes down to the crankshaft and pistons. So if you’re assembling either engine from the ground up, it doesn’t really matter if you start with a 429 or a 460 block. If you’re swapping out the internals, you could take the crank and pistons from a 460, fit them into a 429, and you’ve got your 460. The bore size is the same, 4.36 in, but the stroke is what sets them apart. The 429 has a 3.59 in stroke, and the 460 stretches that out to 3.85 in. Now, to be fair, it’s not quite that simple when you start talking about internal versus external balance, heads, and intakes, but overall, the blocks are identical. The takeaway for performance builds is that either block gives you a solid foundation, and the internals decide if you’re working on a 429 or 460.

So how do you tell them all apart? Well, telling the 460, 429, and 370 apart isn’t always easy, especially with the 429 and 460 since they’re nearly identical on the outside. Fortunately, there are reliable ways to tell them apart using casting numbers and internal components. One of the easiest ways to spot a 370 block is by checking the casting numbers. Since it was cast from a different mold with a smaller 4.05 in bore, the 370 has unique casting numbers. Look for D9TE-DBB, which is specific to the 1979 to 1984 truck blocks and identifies a 370. This makes it easier to distinguish from the 429 or 460. But with the 429 and 460, things get more complicated. These two share the same block casting with identical numbers like C8VE, D0VE, and D1VE, so casting numbers alone won’t help you tell them apart.

To distinguish a 429 from a 460, you’ll need to inspect the crankshaft markings or measure the stroke. Ford stamped alphanumeric codes on the crankshaft counterweights. For 429, look for codes like 4U, 4UA, or 4UAB. For 460, look for 2Y, 2YA, 2YB, 3Y, or something similar. Another clue is on the 460 crankshaft; there’s an embossed nodule between the first main journal and the counterweight, which makes it an obvious identifier once the oil pan is off. But the most reliable way is probably just to measure the stroke. The 429 has a 3.59 in stroke, while the 460 stretches it out to 3.85 in. Measuring the stroke gives you a definitive answer, especially if the other methods leave any doubt.

Additionally, the 370 often used different exhaust manifolds due to its industrial and truck applications. The manifolds were generally more restricted, built for durability rather than performance. In contrast, the 429s and 460s built for performance often had larger manifolds or headers to maximize airflow.

The Ford 460 commands serious respect in the performance world, and for good reason. Its strong block, large displacement, and massive aftermarket catalog make it an awesome platform for builders looking to unlock more power or create a high-performance beast. Whether you want mild upgrades or a full overhaul, the 460 can handle just about anything you throw at it.

One of the first upgrades many builders go for is improving airflow. The stock 460 comes with cast iron heads, which are heavy and restrictive. Swapping them out for aluminum heads from brands like Edelbrock or Trick Flow is a popular move. These heads offer far better airflow and can boost horsepower significantly. Plus, they shave a lot of weight off the front end. For those who want to go all out, stroker kits are the way to go. A stroker kit bumps up displacement by using a longer stroke crankshaft, and in the 460’s case, you can push it to 514 cubic inches or more. These kits usually come with a new crankshaft, rods, and pistons. With a stroker kit, expect massive gains in low-end torque and horsepower, turning that 460 into a freight train of guts and glory.

Now, Ford equipped 460s with hydraulic flat tappet lifters from the factory, but unlike its small block cousins, the 460 doesn’t need block modification to accept a roller cam and roller lifters. This means you can literally grab a roller cam and lifters off the shelf and drop them in, giving you more options and more aggressive profiles. But keep in mind that the 460 wasn’t designed for roller lifters, and the taller lifters can cause geometry issues, which increase wear over time. This is mostly a problem with hydraulic roller lifters along with aggressive cam profiles. So if you’re going roller, it’s best to either run solid roller lifters or keep your cam on the milder side.

Another popular mod is converting a carbureted 460 to fuel injection. While stock 460s in the ’70s and ’80s were carbureted, Ford switched to EFI in the ’90s. EFI conversions provide smoother performance, better fuel efficiency, and more precise tuning. Aftermarket systems like Holley Sniper or FiTech make the swap pretty much a breeze. But if you like to go old school and you’re sticking with a carburetor, upgrading to a larger performance carb is a common move. Stock carbs can be limited, so upgrading to something like a Holley 750 CFM or 850 CFM helps feed the big 460 more fuel and air, which means more power.

Exhaust upgrades are another area where the 460 responds well, and you’ll see a big impact. Installing headers is a common mod that improves airflow and reduces exhaust restrictions. Headers help scavenge exhaust gases more efficiently, which boosts horsepower and torque. Pair them with a free-flowing exhaust system, delivering a serious power boost and an aggressive growl.

Now, if you really want to go all out and you’re looking to push the 460’s upper limits, adding a supercharger or turbocharger takes things to a whole other level. A supercharged 460 can make insane horsepower gains, especially when paired with other mods like aluminum heads, performance cam, and a stroker kit. Turbocharging is less common but still a solid option if you want to force even more air into the engine and extract every last bit of power. Just make sure that your drivetrain can keep up; a stranded driveshaft makes for a really bad day.

So after all that aftermarket pillow talk, are you thinking of swapping a 460 into your ride? Well, swapping a 460 is a popular choice for lots of vehicles. Classic Ford trucks, especially F-series models from the ’70s and ’80s, or even older ones like the F100, are a common fit. The 460 turns those trucks into off-road bruisers or worksite powerhouses. Some builders even drop a 460 into Fox Body Mustangs, though it’s not common for brutal straight-line performance. The 460’s versatility makes it a great option for hot rods and custom builds as well. Muscle cars like the Ford Torino or Mercury Cougar also benefit from a 460 swap. No matter where you put it, the 460 brings the muscle.

So clearly, the appeal of swapping a 460 in can’t be denied. It’s one of the largest displacement engines Ford ever made, and that means tons of power and torque, even stock. There’s also the bragging rights; having the biggest gas engine Ford ever put in standard vehicles under your hood is undeniably cool. It delivers massive performance while staying true to the Ford family. What’s not to love?

Well, there are a few skeletons in the 460’s closet, namely weight, size, and fuel economy. While you’re probably not thinking about saving gas if you’re swapping in a 460, keep in mind that big blocks are famous for guzzling fuel, and the 460 is as big as they come. And while the 460 delivers tons of power, swapping it into vehicles that weren’t originally designed for it comes with a few challenges. As I’ve said just once or twice, the 460 is a big engine. You might need to modify the engine bay or frame to make it fit. Trucks and larger vehicles handle it better, but smaller cars may need fabrication. Also, many transmissions can’t handle the 460’s torque, so upgrading to something stronger is often a must, like a C6 automatic or a modern overdrive transmission like the 4R100 or E4OD.

Also, the 460 generates a lot of heat, so upgrading to a heavy-duty radiator, electric fans, and a beefed-up water pump can be almost a requirement, especially in tight engine bays with limited airflow. Depending on the vehicle, you might also need a custom oil pan to clear the suspension or crossmember. And when it comes to exhaust clearance, headers and manifolds could run into issues, especially in smaller bays, meaning you may need custom exhaust work.

The good news is that there are plenty of swap kits available to make the process easier. Companies like L&L Products and Advanced Adapters offer motor mounts, headers, and other components to help fit a 460 into older Ford trucks or custom applications. They typically include almost everything you need to simplify the swap and avoid extensive fabrication work.

And here’s a fun fact: believe it or not, some builders have even squeezed 460s into Ford Rangers. Now, it’s not an easy fit, but with some modifications to the firewall and frame, the lightweight Ranger paired to the 460 turns it into a wild street truck or drag truck. Swapping a big block into a smaller vehicle like the Ranger offers crazy power-to-weight ratios and, shall we say, a unique driving experience.

As I said just a moment ago, pairing a transmission with a Ford 460 requires something that can handle its substantial torque. The C6 automatic is one of the most common choices, famous for handling massive torque. The C6 was a factory option for many 460-equipped vehicles, especially trucks and larger sedans. It’s a three-speed automatic and one of the most bulletproof transmissions Ford ever made. It’s a good choice for stock or mildly modified 460s. It handles most power upgrades with ease and is widely available, making it common for builds where simplicity and reliability matter the most. But being only three speeds, it’s not great for fuel economy or cruising on the highway.

To help solve that, the E4OD and 4R100 are also popular options. Both are heavy-duty automatics with overdrive, making them great for street-driven builds and towing alike. These transmissions were factory paired with the 460 in Ford’s F-series trucks and E-series vans during the early and late ’90s, respectively. The 4R100, introduced later, is an upgraded version of the E4OD with better internals. Both transmissions offer the C6’s low-end torque handling plus the bonus of overdrive.

While it’s less common, some builders actually opt for a manual transmission with the V8. The T56 Magnum or TKO600 are popular options for those who want full control of the power. As always, it’s important to remember that swapping in a manual transmission means you’ll need a clutch setup, proper bell housing, and pedal modifications if you’re converting from an automatic.

The Ford 460 wasn’t just made for hauling heavy loads or sitting under the hood of RVs; it was built to leave a mark, and it definitely has. Decades after production ended, the 460 still dominates in classic truck restorations and performance builds, cementing its reputation as one of the toughest, most versatile big blocks out there. In the world of restorations, the 460 reigns supreme, powering old school F-series trucks or breathing new life into vintage RVs. This engine is still trusted to handle any job you throw at it. Its reputation as a reliable, torque-heavy engine is set in stone. This engine never gives up, and neither do the people who rely on it.

But let’s not forget the 460’s legacy isn’t just about work; it’s about power. Performance builders love it because once you dig into a 460, it offers limitless potential. Looking for a tire-shredding, quarter-mile scorching beast? 460s gotta cover. This engine still powers drag cars, hot rods, and even some unexpected swap pops. Why? Because it delivers the kind of muscle that turns heads and leaves the competition in the dust.

So after all that, what keeps it relevant? Well, it’s pretty simple: aftermarket support and a dedicated army of builders. Parts are still readily available to rebuild or upgrade this engine into whatever fits your dream build. Whether it’s a street cruiser, towing workhorse, or custom racer, the 460 isn’t some relic; it’s a living legend. For anyone chasing big power or classic torque, the 460 is still hard to beat. Whether it’s pulling trailers or leaving rubber on the road, this engine’s mix of brute strength and upgrade potential guarantees a lasting spot in the hearts and engine bays of enthusiasts for years to come.

Hey folks, Ed here from Bullnose Garage. Today, we’re diving deep into the Ford 460 Big Block V8, an engine that’s basically the Arnold Schwarzenegger of the automotive world—big, powerful, and a little intimidating. Whether you’re looking to restore a classic Ford truck or just want to know what makes this beast tick, stick around. We’re breaking down specs, mods, and why this engine still gets gearheads excited.

The Legend of the Ford 460

The Ford 460, or the 7.5-liter V8, made its debut in 1968 and quickly became a staple in the world of heavy-duty trucks and luxury cars. This engine isn’t about high RPMs; it’s about delivering low-end torque that could probably tow the moon. The 460 powered everything from F-series trucks to Lincoln Continentals, proving that sometimes bigger really is better. Despite its retirement in 1997, the 460 remains a favorite for builders, thanks to a robust aftermarket that lets you turn this engine into whatever you need—be it a dragster or a workhorse.

Engine Specs and Historical Context

Let’s get into the numbers. The 460 boasts 460 cubic inches of displacement, a 4.36-inch bore, and a 3.85-inch stroke. Early models sported a compression ratio of 10.5:1, dishing out 365 horsepower and 485 lb-ft of torque. However, the ’70s weren’t kind to engines, with emissions regulations dropping the compression to around 8:01. By the end of its run, the 460 saw the introduction of electronic fuel injection, making it more efficient and user-friendly.

This engine is hefty, weighing in at about 720 lbs. It’s got a cast iron block and heads, which makes it durable but not exactly lightweight. The firing order is the standard Ford V8 sequence: 1-5-4-2-6-3-7-8. Oil capacity is about 6 quarts, and if you’re thinking about pushing this engine hard, consider upgrading to a larger oil pan to keep everything cool.

Performance Mods to Consider

If you’re looking to unleash the full potential of your 460, there’s no shortage of mods to consider. Start with the basics: swapping out those heavy cast iron heads for aluminum ones from Edelbrock or Trick Flow. Not only do you get better airflow, but you also shave off some front-end weight.

For those looking to go big or go home, consider a stroker kit to bump up the displacement to 514 cubic inches or more. Throw in a performance cam and you’re looking at some serious power gains. And let’s not forget about the option to convert to fuel injection, which offers smoother performance and better efficiency compared to the old carburetors.

Swapping a 460: The Challenges and the Rewards

Thinking about swapping a 460 into your ride? It’s a popular choice, especially for classic Ford trucks. The engine’s size and weight can be a challenge, so you might need to make some modifications to the engine bay or frame. And don’t forget about the transmission—this engine’s torque demands something robust like a C6 automatic or a modern overdrive transmission.

If you’re really adventurous, you might even shoehorn this beast into a smaller vehicle like a Fox Body Mustang or even a Ford Ranger. Just remember, you’ll probably need to modify the firewall and frame. Oh, and stock up on gas, because this engine isn’t known for sipping fuel.

Why the 460 Still Matters

Decades after its production ended, the Ford 460 is still a favorite among restorers and performance builders. Its massive displacement and aftermarket support make it a versatile choice for a range of applications. Whether you’re looking to haul a trailer, leave your mark at the drag strip, or just want the bragging rights of having one of Ford’s largest gas engines under your hood, the 460 delivers.

Howdy folks, Ed here. Welcome back to Bullnose Garage. Today I’m actually out in my bun, driving around, so forgive the bumps and rattles and, you know, some of the noises that happen with an older truck. Today I’m here to talk about the NP435 transmission, which is this puppy right here. That’s what’s in my truck. It is a solid workhorse of a transmission and, uh, it’s certainly worth your consideration if you want to do a, uh, a swap or if you’ve already got one you want to do a rebuild. Uh, it’s probably worth your time. I’m going to get into exactly what everything is, how it works, uh, what all the stats are, that kind of stuff. Keep in mind, uh, this video is Bullnose-centric because it’s Bullnose Garage. So while I know, uh, that the NP435 was used in other vehicles like, um, you know, basically all kinds of vehicles across the board, uh, what I’m going to be focusing on are the Bullnose vehicles, the Fords. So you’re going to see some information in the video that is specific, uh, to the Ford versions. So that’s because I’m a Ford guy, you know, that’s how it works. So while I pop up onto the interstate here and let this engine scream for mercy as it goes into the high fourth gear on the transmission because there’s no overdrive, let’s, uh, go ahead and get into it.

Hello, the NP435. This manual gearbox isn’t just a transmission; it’s a piece of engineering that stood the test of time. Known for its durability and versatility, whether you’re restoring a classic or just curious about what’s under the hood, this guide will walk you through everything you need to know about the NP435, from its gear ratios and shift pattern to the engines it pairs with and how to keep it running smoothly. The NP435 is a four-speed manual gearbox designed with one goal in mind: durability. Built by New Process Gear, a name synonymous with heavy duty, this transmission has been a workhorse in Ford’s lineup since the 1960s. It was a natural fit for the Bullnose trucks and Broncos of the 1980s, providing the kind of robust performance that these vehicles are known for.

Now, what makes the NP435 particularly interesting is its gear setup. You’ve got four forward gears, but they’re not all synchronized. Second through fourth gears are synchronized, making for smooth shifts during regular driving. The first gear, often called the granny gear, and reverse, they’re not synchronized. So if you’re trying to pop into first while still rolling, you’re in for a bit of a grind, literally. But that’s by design because first gear is really meant for when you need serious torque to get moving, especially with a heavy load. So let’s talk gear ratios. The NP435 is known for its particularly low first gear, which is what gives it that reputation as a workhorse. In most Ford applications, you’ll find the following ratios: first gear 6.69 to 1, second gear 3.34 to 1, third gear 1.66 to 1, fourth gear 1 to 1, or direct drive, and reverse 8.26 to 1. There’s also a version with a slightly less extreme first gear at 4.85 to 1, but the low ratio version is what you’ll most commonly find in these Bullnose trucks. That first gear at 6.69 to 1 isn’t something you’d use in everyday driving unless your everyday involves towing a tractor out of a ditch or crawling over boulders. It’s all about giving you the torque to move heavy loads or navigate through terrain with confidence.

The shift pattern on this transmission is pretty straightforward. Here’s how it’s laid out: first gear is up and to the left, second is down to the left, third is straight up in the middle, fourth is straight down in the middle, and reverse, that’s far right and down. Now this pattern is practical, especially for a transmission designed to handle tough jobs. First gear is intentionally out of the way so you don’t accidentally engage it when you’re moving through the more commonly used gears. Moving on to the physical aspects of the NP435, this transmission is built like a tank. The case is made of cast iron, which gives it that characteristic durability but also adds some serious heft. At around 130 lbs, this isn’t the kind of transmission you casually toss around the garage. It’s hefty for a reason; it’s built to withstand the kind of stress that comes with heavy duty use. For the four version, the input shaft, which connects to your engine, has a diameter of 1 and 1/16 in with 10 splines. You’ll also notice a power takeoff or PTO port on the passenger side of the case. This cast iron construction and solid internals are part of why the NP435 has such a loyal following. It’s not flashy, but it’s the kind of component that you can rely on when the going gets tough.

So what can you bolt this transmission up to? The NP435 is versatile, fitting a range of engines that you typically find in Bullnose Ford trucks and Broncos. Whether you’re running the venerable Ford 300 inline 6 or one of the V8s like the 302, 351 Windsor, 400, or even the big 460, the NP435 has you covered. This flexibility made it a popular choice in a wide range of Ford trucks, from daily drivers to heavy duty workhorses. When it comes to fluids, the NP435 calls for SAE 50 weight oil or 80W90 gear oil. You might be tempted to use modern synthetic oils, and that’s fine, but make sure they’re compatible with the brass synchronizers inside the transmission. These old school gearboxes weren’t designed with synthetic fluids in mind, so using the wrong type can cause more harm than good. The transmission holds about 4.5 quarts, and it’s wise to change it every 30,000 to 50,000 miles, especially if you’re working the truck hard. The NP435 typically pairs with the mechanical clutch linkage in these trucks, which is straightforward and reliable. Depending on your specific setup, the clutch diameter usually hovers around 11 in, but there’s some variation depending on the engine and vehicle configuration.

When it comes to transfer cases, the NP435 is highly compatible with several options, making it a favorite among those building serious off-roaders or towing rigs. You’ve got the NP205, a gear-driven, highly durable transfer case that’s pretty much bulletproof. Then there’s the NP28, which is chain-driven and a bit lighter but still solid for most uses. The Borg Warner 1345 is also another option, reliable, chain-driven, and well-suited to off-road adventures. This compatibility with multiple transfer cases makes the NP435 a versatile option, whether you’re building a truck for the trail or the highway. Now cooling, unlike modern transmissions that might have dedicated cooling systems, the NP435 keeps it simple. It relies on air cooling, with a cast iron case acting as a heat sink to dissipate the warmth generated during operation. For most driving conditions, this setup works fine. However, if you’re planning on running it hard, whether that’s towing heavy loads or spending long hours off-road, make sure the transmission gets plenty of airflow. Overheating isn’t a common issue, but it’s something to be mindful of in extreme conditions.

Speaking of running hard, the NP435 can handle up to 450 ft-lbs of torque. That’s a significant amount, and it’s more than enough for the engines it typically pairs with. Whether you’re hauling, towing, or off-roading, this transmission is built to take the stress without breaking a sweat. Driving with the NP435 is an experience that feels more mechanical, more connected to the truck. Low first gear, often called granny gear, is great for when you need to get a heavy load moving or navigate tough terrain, but in everyday driving, most people start in second gear. The shifts are deliberate; there’s no rushing this transmission, and that’s part of its charm. On the highway, the direct drive fourth gear allows you to cruise comfortably, although the RPMs are higher than what you’d see with modern overdrive transmissions. But that’s the trade-off: you get strength and simplicity, but not necessarily the refinement of newer gearboxes. The NP435 shines in situations where durability and reliability are more important than smoothness. It’s excellent for off-road driving, towing, and any situation where you need to trust your transmission to get the job done.

When it comes to keeping your NP435 in good shape, regular maintenance, as usual, is key. Fluid changes are a must, especially if you’re putting the transmission through its paces. Luckily, routine service like this is straightforward, although the weight and bulk of the NP435 can make more in-depth work a bit challenging. Rebuilding the NP435 isn’t overly complicated compared to other transmissions, but it does require some mechanical know-how and the right tools. A full rebuild kit will set you back somewhere between $400 and $700, depending on the quality of the parts. Uh, if you need to replace major components or if the transmission is in particularly rough shape, a professional rebuild might be in order, and that could run you anywhere from $1,500 to $2,500. Given the longevity of this transmission, though, it could be a solid investment. The NP435 is renowned for its durability; with proper maintenance, this transmission can easily last over 200,000 miles. It’s a workhorse designed to handle tough conditions, whether that’s off-road, towing, or just the rigors of daily driving. But like any mechanical component, it does have its potential issues. Synchronizers in second through fourth gear can wear over time, especially if the transmission hasn’t been well-maintained. Bearings can also wear out, particularly if the fluid hasn’t been changed regularly. And if you’re doing a lot of heavy off-roading, the input shaft might show signs of wear sooner than expected. Despite these potential issues, the NP435’s reputation for reliability is well-earned. It’s built to last, and with a little care, it will.

The NP435 has been around since the 1960s, making it one of the more enduring designs in heavy-duty transmissions. Ford used it extensively across its truck lineup, from the F100 to the F350 and even in the Broncos. Here’s a quick rundown of where you might find one: at the Ford F100 from 1966 to 1983, the Ford F-150 from 1975 to 1986, the Ford F250 from 1966 to 1987, the Ford F350 from 1966 to 1987, and the Ford Bronco from 1966 to 1977. The NP435 was favored for its ability to handle the demands of these trucks, whether that was for work, off-road, or just reliable daily driving. And thanks to its popularity and long production run, the NP435 enjoys pretty strong aftermarket support. Whether you’re looking for a rebuild kit, replacement parts, or performance upgrades, there is no shortage of options. Popular modifications include upgrading the bearings, altering gear ratios for specific applications, and modifying the shifter for a shorter throw, especially useful in off-road setups. And this transmission might not have the glamour of modern units, but its reliability and the wealth of available parts and upgrades make it a favorite among enthusiasts.

So that all sounds great. The NP435 is strong, it’s reliable, it’s heavy-duty, and it can handle pretty much whatever you throw at it. And, uh, I’m pulling right out and putting in something different. Ed, Ed, why do you do this? You’re doing this to your 3006, and now you’re doing it to your NP435 too. Why do you keep changing things? Why do you keep pulling the most reliable components out of your truck? Well, to start with, the NP435 is a four-speed with a really low first gear. Now that’s great for heavy-duty tasks, but it can feel a bit clunky and unnecessary on the street, and I’m building a street truck. And I always start off in second gear and can count on one hand the times I’ve used first gear in a real-world situation. The shifts are heavy, and there’s no synchro in first, which means I’ve got to double clutch if I want to drop down into first while rolling. Now for some folks, that’s part of the charm. There’s a raw mechanical feel that reminds you that you’re driving something built to last. But if talking about refinement for a street queen is what my truck will be, the NP435 leaves a bit to be desired. The shifts are more of a workout compared to modern transmissions, and you’re going to feel every bit of that ruggedness in your hands. It’s not the smoothest operator, and on the highway, that missing fifth gear means my Windsor is going to be revving higher than I’m going to like. It gets the job done, but it’s not what I would call a relaxing drive.

So my choice? The ZF5 is a 5-speed manual, and that extra gear makes a world of difference when you’re just out for a drive. For starters, the ZF5 is a more refined transmission all around. It’s got synchronized gears across the board, which means shifts are smoother and easier, even in first. Everything about the ZF5 feels more polished and suited to street driving. The gear ratios are more evenly spaced, which will give me better control over the power from my built 351 Windsor. And where the ZF5 really shines is that fifth gear. On the highway, it lets the engine settle into a nice, comfortable RPM, making for a quieter, more fuel-efficient drive. And you’ll notice the difference right away: less noise, less strain on the engine, and an overall smoother ride. So if, like me, you’re setting up your truck for street use and you want to enjoy those horses without feeling like you’re in a tug of war with the gearbox, I’d say the ZF5 is the way to go. It’s smoother, quieter, and just more enjoyable for everyday driving. The NP435 has its charm, no doubt, but for a refined street experience, the ZF5 will make the truck a joy to drive, whether I’m cruising around town or hitting the highway.

All that said, the NP435 isn’t just a transmission; it’s a testament to durable, no-nonsense engineering. While it might lack the smoothness and refinement of more modern gearboxes, that strength and reliability more than make up for it. Whether you’re restoring a classic Bullnose Ford or just need a transmission you can count on, the NP435 is a solid choice, and it’s built to last. So as you guys can see and probably hear, I’m out here on the interstate going about 65 mph, and that’s about as fast as I can get this rig to go using the, uh, NP435 and my inline 6. And at 65, I’m in fourth gear, spinning about 26 or 2700 RPM, so it’s pretty high. It’d be nice to have an overdrive.

All right, guys, well that’s the NP435, everything that I know or pretend to know about this solid workhorse of a transmission. Hopefully, you learned something; that’s always my goal in all my videos is to, uh, impart knowledge, take the stuff that I’ve learned, stuff that I’ve researched, and pass it on to folks, uh, to maybe help them out a little bit. So you know, now’s the time that I ask, if you really want to support the channel, I’d appreciate a like, a subscribe, uh, drop a comment down below.

Welcome back to Bullnose Garage, folks! Today, we’re diving into a piece of mechanical history that’s been pulling its weight in Ford trucks for decades—the NP435 4-speed transmission. This isn’t your run-of-the-mill gearbox; it’s a rugged workhorse that’s as tough as nails and has stood the test of time. Whether you’re knee-deep in a restoration project, contemplating a transmission swap, or just curious about what makes this beast tick, you’re in the right place.

What is the NP435?

The NP435 is a four-speed manual transmission that was designed with one primary goal in mind: durability. Built by New Process Gear, this gearbox has been a staple in Ford’s lineup since the 1960s. It’s a natural fit for the Bullnose trucks and Broncos of the 1980s, known for their robust performance and no-nonsense engineering.

Gear Ratios and Shift Pattern

Let’s talk numbers. The NP435 sports gear ratios designed to maximize torque, especially in first gear. In most Ford applications, you’ll find a first gear ratio of 6.69 to 1, which is fantastic if you’re looking to pull a house off its foundation. Second gear is at 3.34 to 1, third at 1.66 to 1, and fourth gear is a 1 to 1 direct drive. Reverse comes in at a steep 8.26 to 1. This setup is perfect for heavy-duty tasks, but it might feel a bit out of place on your daily commute.

The shift pattern is pretty straightforward. First gear is up and to the left, second is down to the left, third is straight up in the middle, fourth is straight down in the middle, and reverse is far right and down. It’s practical and keeps you from accidentally hitting that granny gear when you really don’t want to.

Physical Characteristics

If you’re thinking of getting yourself one of these, be prepared for some heavy lifting. The NP435 is built like a tank, with a cast iron case that adds up to a hefty 130 lbs. This weight isn’t just for show; it’s what gives the transmission its legendary durability. The input shaft measures 1 and 1/16 inches in diameter with 10 splines, and there’s a Power Take-Off (PTO) port on the passenger side for those extra accessories.

Engine and Transfer Case Compatibility

One of the things that makes the NP435 so versatile is its compatibility with a range of engines. Whether you’re running a Ford 300 inline 6, or a V8 like the 302, 351 Windsor, 400, or the big 460, this transmission fits right in. As for transfer cases, the NP435 plays well with the bulletproof NP205, the chain-driven NP208, and the reliable Borg Warner 1345.

Maintenance and Potential Issues

Keeping the NP435 in working order isn’t too difficult. It takes about 4.5 quarts of SAE 50 weight oil or 80W90 gear oil, and it’s wise to change it every 30,000 to 50,000 miles. While it’s a tough nut, it’s not indestructible. Synchronizers in second through fourth gear can wear over time, especially if the transmission hasn’t been well-loved. Bearings can also wear out, and if you’re doing a lot of off-roading, the input shaft might show signs of wear sooner than expected.

Why I’m Swapping to the ZF5

Now, you might be wondering why I’m swapping this beast out for a ZF5. Well, while the NP435 is a champ at handling tough jobs, it’s not exactly the smoothest operator for street driving. The ZF5, with its extra gear and synchronized shifts, offers a more refined driving experience, especially on the highway where that missing fifth gear in the NP435 means higher RPMs and a noisier ride.

Final Thoughts

The NP435 might lack the smoothness of modern gearboxes, but its strength and reliability are hard to beat. It’s a solid choice for anyone restoring a classic Ford or needing a transmission that can take a beating. If you’re setting up for street use, though, consider something like the ZF5 for a smoother, quieter ride.
