I have checked everywhere and I still can't figure out what block is in my truck.
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.
