The GMC is a better motor than the Chevy. Better iron and full pressure oil. The motor from the '50 is probably a splash oiling 216.

But you should run the Chevy motor and ship that GMC to me.

Unless you care about being original you will probably be happier with that 270. I run one in my '55 1st Suburban and love it. I certainly would not take a GMC out to put a Chevy it!

It's true. I really don't do anything but browse the Internet looking for trouble...
