Softer "modern" clutch set-up may help extend rear-end life in 10-bolt over what your brother experienced...but if he builds stick car...ONLY a 12-bolt should be used in the '57.

Your brother should have used a Dana in the conditions you mentioned!

IMHO...the '57 150 being not that heavy, and the smaller carb(s) limiting rpm a bit (depending on which combo he ends up with ), the gear ratio wouldn't have to be that "steep", and tire diameter/gear would be sorted out in testing. If considering to keep the car original and running AUTO TRANS, I still think the early 10-bolt has a chance but to be practical...you'd have to be able to do most of the work yourself . Mike T. makes some good points too.....
