Hi Dan,

Same rear gears, so probably just as slow.

I'm building a '55 1st GMC 1-ton as a driver/trailer puller. I replaced the rear with a GM 14-bolt with 3.42 gears and I'm putting a Cadillac 500 in mine so speed won't be a problem.

I'm swapping the IFS crossmember from a 70's 3/4-ton under mine to provide disk brakes and power steering.


1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more...
It's true. I really don't do anything but browse the Internet looking for trouble...
