1980-1986 Ford 351: Windsor vs M vs Cleveland

Alright, if you’re trying to identify whether you’ve got a 351 Windsor (351W) or a 351 Cleveland (351C) under the hood, here are some key features to look for:

Identifying a 351 Windsor (351W)

• Valve Covers: Typically, they have five bolts.
• Thermostat Housing: Located on the intake manifold.
• Timing Chain Cover: Made of stamped steel and is separate from the engine block.
• Block Design: Generally taller and narrower compared to the Cleveland.
• Distributor: Sits directly in front of the intake manifold.

Identifying a 351 Cleveland (351C)

• Valve Covers: Usually have eight bolts.
• Thermostat Housing: Integrated into the engine block, not the intake manifold.
• Timing Chain Cover: Cast into the block, giving it a more unified look.
• Cylinder Heads: Larger ports and distinct canted valve arrangement.
• Block Design: Wider appearance due to the larger heads.

Quick Tips

• Check the Casting Numbers: Located on the engine block near the starter. This can confirm the engine type.
• Visual Cue: The Cleveland’s heads look wider and flatter due to the canted valve design.
• Location: The thermostat location is a quick giveaway. Cleveland has it built into the block, while Windsor has it on the intake.

If you’re still unsure, taking photos and comparing them to guides or online resources can help. There might be a useful video or article on the Bullnose Garage channel or website that breaks down these differences visually.

Hey there! Adding A/C to your Ford 300 (the inline-six) is definitely doable, and it shouldn’t make your truck hard to run if done right. Here’s what you need to consider:

Engine Load

• Power Draw: The A/C compressor will put an additional load on the engine. The 300 has plenty of low-end torque, so it typically handles the extra load well.
• Performance Impact: You might notice a slight dip in acceleration when the A/C is running, especially at lower RPMs.

Cooling System

• Radiator: Make sure your cooling system is in good shape. Consider upgrading to a higher-capacity radiator if you’re dealing with extreme temperatures.
• Fan: Ensure your fan and shroud are efficient. An electric fan can also help manage engine temperatures better.

Electrical System

• Alternator: Check if your alternator can handle the additional electrical load. A higher-output alternator might be necessary.
• Wiring: Ensure all wiring is up to spec and properly insulated to prevent any electrical issues.

Installation Tips

• Compressor Mount: You’ll need a compatible bracket for the A/C compressor. These can sometimes be found in salvage yards or aftermarket suppliers.
• Belt Routing: Check belt routing for proper tension and alignment. Sometimes a different belt length might be needed.

Pro Tip

• Idle Speed: You might need to adjust the idle speed slightly higher to compensate for the compressor load, especially with a manual choke.

Adding A/C is a great upgrade for comfort. As long as you keep an eye on these factors, your truck should run smoothly. If you need a detailed walkthrough, there might be guides or videos on the Bullnose Garage channel to help out.

Choosing the right muffler for your Ford 300 inline-six can enhance performance and sound. Here’s what you should consider:

Performance Goals

• Stock-like Performance: A quieter muffler, like a Walker or stock-style replacement, keeps performance close to factory specs with minimal noise.
• Improved Sound: A performance muffler like a Flowmaster 40 or 50 series can give a deeper tone without being too loud.
• Increased Flow: For better exhaust flow, consider a straight-through design like a MagnaFlow. It offers gains in power, especially if other engine mods are in place.

Sound Preferences

• Quiet and Subtle: Chambered mufflers are great for a subdued sound.
• Deep and Throaty: A glasspack or straight-through muffler will give a more aggressive sound.

Installation Considerations

• Fitment: Ensure the muffler’s inlet and outlet match your current exhaust system diameter (commonly 2.25-2.5 inches for these engines).
• Space: Check for adequate space under your truck to accommodate the muffler size.

Pro Tips

• Rust Resistance: Go for stainless steel if you’re worried about corrosion, especially in areas with harsh weather.
• Backpressure: Keep in mind, reducing backpressure too much can affect low-end torque, which is important for the 300’s performance.

Choosing the right muffler for your Ford 300 inline-six depends on the sound and performance you’re after. Here’s a rundown of some good options:

Considerations

• Sound: Decide if you want a mellow tone, something more aggressive, or a quiet ride.
• Performance: Look for a muffler that won’t restrict airflow, helping maintain or even improve performance.
• Fitment: Check the available space under your truck and the exhaust diameter to ensure compatibility.

Popular Muffler Options

   • Sound: Aggressive and throaty.
   • Performance: Offers good flow and power.
   • Notes: Can be loud, especially at highway speeds.

2. MagnaFlow Performance Muffler

   • Notes: Good option if you want a quieter ride.

4. Cherry Bomb Glasspack

   • Sound: Classic, raspy sound.
   • Performance: Straight-through design for good airflow.
   • Notes: Can be quite loud and might drone.

Pro Tip

• Exhaust Size: Stick with a 2.25" to 2.5" exhaust system for optimal performance with the 300.
• Tailpipes: Consider adding a resonator if you’re worried about drone on the highway.

If you’re still unsure, there might be reviews or sound clips online, and possibly some related content on the Bullnose Garage channel to help make your decision.

Choosing the right muffler for your Ford 300 depends on the sound and performance you’re after. Here are some options to consider:
