904 Trans for 500 HP?

wow, i did not expect this much positive feedback about using the 904, seems the way to go for me.

Is there any good literature to read before i tear into one? On the other hand, how much is a stout street / strip 904 from a builder in U.S.? If not too much dough i´ll consider this, too. Maybe some of you can tell me some shops that know their stuff.

Does a quality rebuild kit, maybe from A&A transmission, contain all the parts i´ll need if i do it myself?

i know, a lot of questions...with your help i´m getting there!
