Simple bolt ons for torque?
I have an 86 f150 fi302. I am looking to add more torque to give me better fuel effeciency without goin to far into the motor at the moment. I was wonderin what yall had in mind.
I am lookin at a cold air intake, throttle body spacer and the tornado fuel saver. Eventually i am goin to dig deeper into the motor but as of right now im just stickin with simple bolt ons or easy install parts. Thank you for all your help. I would like your opinions on these and anything else you could think of to help me out. thanks.

There is almost nothing outside the motor that you could change that will make any appreciable difference to TQ production.. except the exhaust system. The factory system is all about low noise and emissions, the better you make it flow the more TQ and milage you get. And just to be clear making it bigger is not necessarily what I mean, a stock 5.0 has no use for anything more than a single 2.5" exhaust. The choke points are in the manifolds and stock Y-pipe and cats, swap these for headers and a high flow cat and you'll feel the difference. Once that is done the next stop is inside the motor with valvetrain upgrades.

the cold air intake will improve milage some, but dont waste your money on throttle spacers or 'fuel savers' they just dont work.
For your EFI motor there may be computer tuning availible to increase gas milage. Another thing to look into is a set of underdrive pulleys.

The stock intake system is a real cold air system meaning it draws air from outside the engine bay, most of the aftermarket K&N style open air filters are not and will have no positive effect on a stock motor except to make more noise. The stock airbox is also more than sufficient for a 302.
This vintage of EFI system neither requires nor benefits from "tuning" like the newer OBD-2 systems, it simply responds to the airflow requirements of the motor so all you have to do is make the motor flow more air. 1 thing you can do is advance the timing, this will produce more TQ and HP but you can only advance so much before detonation becomes a problem and you have to use premium fuel or back the timing down a bit. Many of these motors will tolerate 2-4 degrees additional timing from the base of 10 degrees initial.
