Questionable decisions!

Heres some pictures of what I'm working with, found that it's actually a 904 not a 727 - would it be better to work with a different transmission? I will take a better look at my other options now that I'm working in this direction.

I'm not doing anything to this 5.2l at the moment, just popping it in and running it refreshed with new chain and seals/freeze plugs. I havent cleaned this trans, it being clean inside the bell and the fluid looking good is why i had chose it, no other reason
