search 904 recipe here. There is a list of parts that will make a 904 run.
904 race tranny Recipe
For a kit to start with transtar 12008C from northern auto for about $100. Buy the other stuff in the recipe.
I don't run anything but the stock clutches. Put 5 in the front drum using thin rear frictions/steels. It won't be $200 cheap to rebuild it, but with the right parts, it will hold up fine. Plenty of stroker SB's running transbraked 904's out there.
There is a reverse wound spring so the 24 spring kit may not be required. Probably a bunch less $
No expensive front drum required using a 904, that's a 727 issue!
Just say no to low stall converters :)
