Hey guys. New to the site. Just wondering what you guys think the value of an LS6 454 crate motor would be? Bought new in 1988 and never fired. I think I have located one. Just wondering what a fair price would be for it. Thought you guys could offer the best info.

Wow. I'll bet lots of money. I couldn't put a number on it but I bet someone will. Welcome to the site and these guys will steer you in the right direction.

Probably not any different than any other crate engine. They were like $2700 new then. They are not the original LS6 replacement engines. They were rect port open chamber 10.25-1 compression engines. I looked at them for my Malibu. They were rated at 450 hp I think, but it was either that or the 12.5:1 compression LS7 crate engines.
