I know that crate engines don't usually have the casting code so I'm thinking its a crate? I was told when I first bought it that it was either a 71 or 77 (can't remember the year he said) corvette engine. I think it's a 71 because he also had a 71 stingray at the time an I think he put that stock engine in the elky. Any ideas? If u need pics to maybe help just say so. Please and thanks guys.
Use the casting numbers and date code
. If there is no suffix code, it was removed during block decking or was never there in the first place (OTC block or possibly a replacement engine).
