I'm an Olds guy, but even I think there should be a Pontiac motor in a Firebird. If the 81 was originally a 301 motor, you should have all the parts needed to bolt in a Pontiac 400 or 455. The Olds motors in Firebirds use the Chevy-style frame mounts with an Olds-unique bracket that bolts to each side of the block and adapts to the Chevy frame mounts.
