904 rebuild/swap advice

just so we're all on the same page, we're talking about the A-904G. The three speed that comes on a 225 right?

'cause to hear ya'll tell it and to look at summit racing's stuff this thing can actually put down some power.

and even though it's a dumb question, the A-904G is or isn't the same thing as a Torqueflite A-904.

You'll have to forgive the dumb questions, I've never done a ground up rebuild before and i'm still learning all the mopar lingo.
