stock looking engine , BIG POWER |||

I built a 383/496 two years ago. One stock appearing at Carlisle that year. Through manifolds it made 450hp to the tires. He's since made some bolt on changes and it now makes 480. But it can be done. If you were to start with a running engine (core) and go from there, you'd belooking at $12-13K for it. Ported Stealths, solid flat tappet, no need to port the manfolds by the way. Totally not worth it. Having the right cam is what matters.
