Quote: so are you saying that you feel 670 HP out of a 416 is about the max you can make in a 59* motor? i think we've done better than that. 670hp makes a nice combo but c'mon. if that's the limit were all in big trouble. even some of the chevy 383's we've done make more than that. no point in rubbing salt in the wound by talking about the SBC 434's we've done, LOL.
Would you care to post the numbers run including weight with these higher HP engines? That would be a fairer comparison. My guess is you have a liberal dyno, or better yet a more liberal dyno than Ryan has.
