I seen this engine inside a '69 Corvette running. The number of months later the Corvette owner remove the engine and put a 496 cubic inch and the Corvette.
I purchase the engine off of him and it has been sitting at my shop undercover ever since. Don't look I'm going to use it anytime soon up for sale!
It's stamped high performance on each side of the engine. I don't know much about engines overall idk much about engines but it is stamped high performance and I did see this engine running in the Corvette.
