I am in the final stages of a frame off restoration a '74 Bronco for my brother, and I need some suggestions. It is going to have some 31" tall tires and a 4" lift. It has the original 302 with a 268 H cam, Performer intake, Autolite 4100 and Headman headers. It has a C-4 with an un-determined stall speed. What would be a good choice? It has 3.50 gears front and rear. I want to know what a good gear will be with the 31" tall tires. I don't think the 3.50's will cut it as it will probably be gutless on the low end. I am thinking 4.11's, but I wanted to see what anyone else thought. It is pretty much going to be driven on-road with an occasional trail ride. It will be primarily driven on the freeway to my bro's work, so the RPM's will have to be reasonable.
