The 351 Windsor is a sturdy engine that can handle a good amount of horsepower, especially if properly built and maintained. Stock, the 351 Windsor from 1986 makes about 150-200 horsepower, depending on the specific configuration.
If you’re looking to increase its performance, many enthusiasts have successfully pushed these engines to around 400-450 horsepower with the right modifications, such as upgrading the intake and exhaust systems, adding a performance camshaft, and possibly rebuilding the internals with stronger components.
Just remember, with great power comes great responsibility! Make sure your transmission, rear end, and brakes are up to the task if you’re planning to boost the power.

What is the horsepower output with a 4.10 ratio and 31-inch tires?
How does the 450hp with a 4.10 ratio and 31-inch tires affect 0-60 times?
Estimating 0-60 mph times can be a bit tricky since it depends on several factors, including weight, traction, and tuning. However, with a well-tuned 1986 Ford F150 equipped with a 351 Windsor producing around 450 horsepower, a 4.10 gear ratio, and 31-inch tires, you’re likely looking at a 0-60 time in the ballpark of 6 to 7 seconds, assuming good traction and a proper launch.
Keep in mind that a lot of variables can affect this time:
-
Weight of the Truck: If you’ve got a lot of extra equipment or a heavy load, that will slow you down.
-
Tires: The type of tires you have can significantly affect grip and acceleration. Performance tires will give you a better launch than all-terrain ones.
-
Transmission Type: If you’re using a manual transmission, your shifting skill will play a big role in your acceleration. An automatic with a good torque converter can help you get off the line quicker.
-
Tuning and Fuel: Proper tuning and using high-octane fuel can help you maximize that horsepower, leading to better acceleration.
-
Launch Technique: How you launch the vehicle can impact your times. Too much wheel spin or launching without enough power can slow you down.
