741 was standard even on the 383 four speeds, and they can take abuse. I found that all the C body cars I've had used 742 cases, at least the 383 and 440 cars, so you could put something together that way if you want the 1 3/4 vs 1 3/8. My 383 GTS has a 741 case, but I didn't realize the housings twisted under hard use, but I'm old and 40mph is about it for me.lol
