Greetings, ZDADDY!

This engine was specifically designed to be a true V-6 engine having no relationship to any other GM V-8 engines, and was engineered long before Chevy even thought of manufacturing the 454 V-8 engine. The internal parts are much beefier than the 454 internals, and are not interchangeable.
