I have a 3.08 in my '55 1st Suburban with a GMC 270 and an SM420. It works real well as a daily driver, but pulling a trailer with it does not work as well as I'd like.


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...
