Have you thought about a T-10 or a close ratio 3 speed. I won a bunch of of drag races with both types of Borg Warner's. Had a few aluminum case 4 speeds but, I'm a little set in my ways. I prefer cast iron, hey it's weight down low on my 57-150 and it helps the front from bouncing up a little too much. Pending which rear end I'm running I get very good performance on the close ratio 3 speed. Either one will fit right in nicely with no modifications. Listen to Jerry he is a pro. No brag, just fact. doc
