i blew my 350 up and i built my 383 finally it dynod on the motor dyno at 500hp and 560lb ft tq. i have a 700 r4 with a b&m shift kit and stock stall now and i know it will die when hooked up to that. so i was thinking turbo 400 or something, i was looking at the TCI super streetfighter trannys, anyone have any suggestions. what do i have to buy to swap a 400 in where the R4 was, problems, etc?
