help needed with 904

Well here we go I hate starting the complete overhaul basically on the 6th page of this thread but Whatever it's going to happen. So everybody should know or should know by now this is one of two freebie 904 Transmissions that were tossed in with a couple $50 Craigslist small blocks. Really just watching those videos with the guy and the beginner has completely inspired me to tackle this what looked like very simple job. I'll probably have to invent some new curse words That actually I thought I used them all up making that four Speed work ( not rebuilding it that was easy)
So I believe stay with the tradition of the $50 Craigslist rebuild I had to keep this on a strict budget more so because I have to LOL as always I have no budget. Of course being a drag racer at heart or at least racer and anyway I would do some small modifications that were inexpensive no problem but I just would rather keep this more of a learning experience so if I do one or the other one I can click through it easily and put all the high-performance stuff into it?
