Rebuild 904 or swap for 727?

The 904 fans defend their tranny vehemently, but 727 guys generally just keep their mouth shut. The 727 is the trans that is consistently tested behind thousands of horsepower. Rarely do you see a 904 in that position. WHY? BECAUSE THEY DON'T FIT A BIG BLOCK. Catastrophic breakage in a 727 is common because they are subjected to twice the horsepower than the 904; and on a regular basis. Is a hemi owner going to try a 904 behind his 1,200 horse motor? He would laugh you off the track. If you wanna feel good about your lil 904, then more power to ya, but they're just like C4s; builders love them cuz they're making money off them; not cuz they're good transmissions. Builders can't make the big bucks off a 727 cuz they're just aren't enough customers. I myself have a built 904 behind a mild 360 in my 66 Dart, but if I had a 408 I'd modify the floor and firewall and run a 727. Running a 904 to get an extra fifth of a second in the quarter is the only good reason; otherwise you're just buying into the scam and spending a ton of money on something that will never be comparable to a 727. The folks who understand this won't chime in cuz they don't want to be attacked (and misquoted) by the fanatical horde. Do yourself a favor, don't buy into the 904 hype and just run a 727 if you can.
