Hey I was thinking about takeing my old 3 speed out of my 55 1st series truck and putting a 700 r4 in. I was wanting to know if anyone on this page could tell me if they had ever done anything like this before? Any if so what to look for what will work and what will not, and do any of you guys think that a 350 turbo might be the way to go, I have already put a 79 carmero 3:75 gear rear axle under my pickup but I want to stay with the 235 stovebolt and also I have not subframed! any help you guys can give will help me. Thank for looking.
