Wow, you’ve got quite the setup on your ’86 F150! It sounds like a beast! With that combination of a 351W, performance headers, a tuned carb, and a beefy 5.13 gear ratio, you’ll definitely notice some serious power and torque.
Here are a few tips to help you get the most out of your setup:
1. Fine-tune Your Carburetor
Since you have a tuned 750 cfm four-barrel carb, make sure it’s jetted correctly for your engine’s performance mods. You may want to experiment with different jets and power valves to optimize performance, especially under load.
2. Ignition Timing
With an upgraded ignition system, ensure that your timing is dialed in. A good starting point for a performance cam is around 32-36 degrees of total timing. Just remember to adjust it based on how the truck runs and any detonation you might hear.
3. Exhaust System
Since you’re running straight dual exhausts with performance headers, ensure you have quality flowmaster or similar mufflers to maintain a good balance of sound and back pressure. This setup should give you a nice growl while maximizing performance.
4. Suspension Setup
With your upgraded suspension, make sure all your components are properly aligned and in good condition. This will help with handling, especially off-road. Consider using heavy-duty shocks to complement your lift and improve ride quality.
5. Tire Selection
You mentioned having 28×10.5 tires. With your gearing, you might find that you can handle larger tires if you want to go bigger on the rubber, as discussed earlier. Just keep in mind your clearance when considering larger sizes.
6. Gear Ratio
Running a 5.13 gear ratio is great for off-road and towing, but it might be a bit low for highway driving. If you plan to hit the freeway often, you might want to consider a different set of ratios for better fuel economy at higher speeds.
7. Regular Maintenance
With all these performance upgrades, regular maintenance becomes even more critical. Change your oil regularly, keep an eye on your coolant levels, and make sure to inspect your drivetrain components frequently to catch any wear and tear early.
