Need opinion 904 or 727

The numbers I've heard is that anything below 600hp a 904 can be built fine.

Biggest problem with the 727 is the rotating weight. If you overspeed the thing in a burnout, that is the danger

I just heard anything below 725 + hp is good on a 904 . Times have changed , I exploded 3 904 transmissions back in the 70's . Hole trough the case in 2 , all were put in the garbage , cases were not usable , replaced it with 727 never had a problem .
