Maximum HP in 904 Transmission With the following parts:

I vote for a sticky from Chris Andrews Racing,on how to build the 904 for a small block running anywhere from 400-600hp.Mine is working great from his advise.

I second that! I've been buildin um a while but found out today there's even more you can do on a street build. That's a great idea. The two transmissions are so similar, he could probably make recommendations on both as he went along.
