I am looking for more detailed info on auto trans behind a 4G63 narrowblock. I have heard that a baby 904 should bolt up, but have no way of confirming this. i most likley will end up with the BR adaptor, Torque converter and flywheel, unless there is something off the shelf that will bolt up with minor machine work?
I actually spoke with someone at Buschur Racing today, they sell the adapters too fit a T-350 , T-400 , or a GM Powerglide Automatic Transmissions to a 4G63 they go for around $250-350
