Okay, well, lets talk about it some. This is the original slant 6 904 that will go back behind the built up slant. Other then the silly 727 into 904 stuff, I've also heard to empty the 904 case and install A998 or 999 internals. What problems will I run into trying that? Could I just install the drums and gearsets? Maybe the input shaft? Or are other parts from the original 904 still too weak? Any writeups on doing this anywhere?
