454 in a C10!!!
Don't feel bad, there has been plenty of 145hp 350 v8 chevys also.
I don't feel bad at all, as good as it runs - especially with all the miles it has on it! A friend of mine from the Naval base crammed an old caddy engine in a Lil ol' Chevy Luv truck. Originally he was gonna put a 350 in it, but somebody bet him he couldn't put the 500+ instead. So seein' as he was a Marine...
