All I know is that the original block froze one year and split and the truck had a new motor put in but the spot beside the dist isn't stamped and the casting numbers make no sense to me at all.
Is there any other way to get the engine size. I am going to buy new main bearings and rings for the engine since it sat so long but can't without knowing the size. | | | | | Joined: Oct 2003 Posts: 5,152 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Oct 2003 Posts: 5,152 | Pictures, casting numbers, and measurements of the bore and stroke might help.
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... | | | | | Joined: Feb 2009 Posts: 400 'Bolter | | 'Bolter Joined: Feb 2009 Posts: 400 | If you can post the casting numbers someone here should be able to tell what it is.
