I am not saying a max effort W8 won't do the job but what would one of those pro stock truck heads cost complete and assembled with springs nessacary to handle the cam nessacary to turn a 500 inch motor effectively 7500 RPM? That is why no one builds 500 inch SBMs





The average guy isn't going to spring the cash for a custom Bryant crank, so it's a moot point. I don't imagine kits like this appearing in anyone's catalogues anytime soon. JMO anyway
