If you have the Cadillac 500 I'd sure suggest going with it over the Olds, though those I know running the big Olds are pretty happy with it.

I'm planning to put a Cadillac 500 and TH400 in my GMC 1-ton.


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...
