Re: Newbie thinking about diving into a '65 GMC 1000
I'd bet money that's a 230 or 250. Engine numbers will be on the lower side of the Block near the starter.
If the side covers are 4 inches tall it's a 230 or 250.
6 inches tall it's a 292.
Dished pistons. 250
Flat top pistons. 230 Easiest way to tell.
