.....not trying to be overly negitive and cause a problem but I blew up a 700R4 years ago that was behind a small block w/ 499 Ft. Lbs Tq. & 438 HP {same motor that's going in my '32 but with a little bit bigger cam}. I'm now going w/ a turbo 400.... Anyway the 700R4 was in a 2800 Lb Camaro w/ a 2400 stall. The trans was professionally built & was supposedly able to handle this much HP but it just didn't.... Again, not trying to bum anyone out but I did have problems with mine & it wasn't behind a big block either. I for one would not use a 700 R4 unless it was in a low HP application... Bill
