I have a 91' f-one fiddy xlt 4x4 ext cab. It has the 302/1356/and aod setup. I love to tinker and upgrade. How much extra wiring and PCM work will I have to do to do the 460/NP205/C6 swap? Are those the better items for a pure power swap? I don't think I will mess with the d44 and 8" axles. I want to run a 35" Tire. Looking forward to input, thanks gang!
