1985 Ford F-150 Supercab?

How can I increase torque in my truck? What parts and services do I need?

302 5.0 V8 engine

Change the cam profile and intake/carb combination, add free flowin (headers) exhaust - call edelbrock for recommendations for increasing torque/torque curve - 302 is common and the question has probably been asked and answered a lot of times in the past.

Fit a larger engine. More torque? Any more and the transmission will give up.

Simplest way would be to transplant a somewhat larger 351 Windsor engine. What I did on both my 1982 F100 AND my 1995 F150.
