Engine swap
My son bought a 86 F-150 with a 302 with a broken crank. The truck came with a 302 out of a 86 mustang. The mustang engine is a high output. Someone has told him he will have to change the cam to get it to run right. Has anyone heard of this?

My guess is gonna be: it depends on how you want to use the truck.
Mustang engines are high RPM, high horsepower power plants.
Truck engines are generally lower horsepower but higher torque, as it's low-end torque that is
most useful in work trucks, not high-rpm horsepower.
And, a truck weighs a helluva lot more than a Mustang....

If it's a high output engine no need to change the cam, just makesure you use the correct firing order, it's not the standard 15426378 but the other one. Don't worry about high RPM pwer vs low end torque... Stock motors in any Ford are low RPM deals and will be fine. If you want more power build a 460, for light duty getting around and such a 302 will be fine but won't get you there in a hurry.
