Hey guys! I blew up my stock c4 in my 69' coupe during my last run at the strip I was going to rebuild it with broader's stuff but i kinda wanna do a t5 conversion so i have an overdrive gear and i wont have as much power loss through a manual trans. How durable are these trans? the motor is a 331 with high 300s at the rear wheels and it has an explorer 3.73 8.8 rear end. Whats a good company to use for durable parts? And what parts are needed to be changed for this much power? this car will be 50/50 drag/strip and i might be spraying it, not sure yet though. And anyone that did this with the 8.8 rear end swap, is there any drive shaft issues? Thanks guys!
