whats the strongest trans between the two trying to figure out what way to go ive heard good things about them both
As 66Satellite mentioned, with less rotating mass and smaller internals, you might run a bit quicker but the 904 won't last and if you don't mind R/R the trans, is it worth the hassle?? Just my thoughts!I read that article thats what got me thinking what was the best way to go
Thanks DougThe biggest issue with a 904 is cracked converter hub. If you convert the the pump to to drive the converter with flats on the hub instead of notches problem is solved. Use the multi spring front drum conversion. Besides that it wouldn't scare me in a 10 second car with stock parts and a good valve body. Now if you want to bracket race into the 9 second zone with no maintenance I'd use a 727.

I’m going to run a 3rd gen hemi in my car thanks for your inputI'm always a little leery of the magazine "build ups" & this one seems very superficial in description of components needed to stand up to a 9 second Gen 3 Hemi. It depends on what your torque, power and intended use is. "Racers of the day" that switched from a 727 to a 904 were mostly the "class" racers that needed every .01 second at the track. They also tended to spend the money on the specialty parts needed to make a 904 even remotely close to a 727 in reliability. With a fairly mild small block, I suspect a 904 would be just fine.
