Tranny Recommendations for 600 HP

2 cents......

My 408 is probably in the 550 hp range, pretty stinking radical. John Cope built my 904. Zero issues, awesome tranny, crisp as a cracker. Was at St. Louis Monster Mopar a few years back and he said he probably built more than 50 of the trannies running there that day. Again, he knows Mopars. But he is in northern Indiana.
