727 vs 904?

904 hold very well behind a small block 340 or 360, if you are burning them up then find someone else to rebuild them for you...

I have been doing my own for 10 yrs now..and I am no expert....I have had two 904 that had problems ..both were my screw up...rolled a lip seal...and forgot a spacer...LOL...

Refreshing one now that has been his service since 1992.....We have 3 cars that race and all use transbrake......
