I like 360's. My 3300 pound Dart( with my 315 behind the wheel) has already been 11.20's with a bone stock factory shortblock and a 727 with mismatched convertor.
Swapping to 904 and will have converter specced to the combo this offseason. Will run in the 10's after the changes i am positive. I shift it at 6 grand, makes power not having to run it hard.
