Right now I have a TH350/NP205/GV overdrive setup in my 76 Blazer. I want to swap in a 700r4, probably from Bowtie Overdrives, keeping the NP205 and selling the GV unit. Anybody do this swap? I've searched on this topic but haven't found any definitive stuff. What are the issues? I understand the 700r4 is about 6 inches longer. From what I know so far, the tranny bolts right in, the lines to the radiator are pretty similar, and BO has a kit that makes doing the TV cable easy. How about the TC being farther back? Fabricated levers? /forums/images/graemlins/dunno.gif New hole in the floor? /forums/images/graemlins/hack.gif I can order the BO tranny w/ the NP205 conversion shaft installed.
