Zonk, My son and I have been working on a similar project..tired engine and tranny. We tried the TCI "street fighter' from Summit racing. After talking with TCI they assured us it would work well for street use. It bolted right in. The problem was that it shifted from first to second around 50 mph and into third was way up there and very hard shifts. felt like the drive line was going to snap..and this was at normal driving acceleration too. after calling TCI they said we had the wrong shift servo..they sent us a new servo and it shifted the same way..Summit racing did take it back and we got a full refund. We ended up just rebuilding the original C4 with heavy duty parts and a shift kit from "transgo" very happy with it.
About 4 months ago we installed a ford racing 302 (M-6007-XB3) in it. It was a fairly easy swap. You do need a few parts off the old motor to make things work. He has a RPM intake with a Edelbrock 650 carb. Go with the 'steel' distribtor gear and not the broze one. It is a great combo for everyday driving.
