I'm trying to help a friend sort out what he needs to convert his 51 Chevrolet car with a three speed and closed drive to open drive. The car now has a 235 (or is supposed to) and the stock 51 bellhousing.

Can he use the stock bellhousing or does he have to swap to a later bellhousing or a pickup bellhousing as someone suggested to him?

He pretty well has the rest of it figured out but needs this info before he starts pulling it apart.


1948 Chev pickup.
