Alright I know to search and i have but just end up circling around and not getting a straightforward answer for what I wanting to know. Im sure this has been beat to death on this forum. I have an 85 z28 v8 5 speed, Im fixing to yank both out and put a big block in. Im going with an automatic so first question, If i go with th350 will my driveshaft work and can I just buy the bm bracket for the torque arm and use my crossmember? Or if I go 700r4 will I need a diff crossmember and driveshaft? Please help

 

Thanks for the replies I found the answer
