If it was me I wouldn't sweat it. I'd drop it in run and drive it. Even if it is a turd it would be much funner to drive a big block dart than to not drive a big block dart! Funner, more fun, more funnest? I don't know im just saying it would be fun to drive it rather than it setting without an engine! Lol
