Here is a engine we just did. Its a 496 with the same cam and compression on pump gas. It has Max Wedge Port SR Heads as received from Indy with NO porting, just our valve job. It has a 440-2 Intake and a 950 Quick Fuel.

With the 440-1 Heads and the 400-3 Intake with a 4500 Carb it will make more than this with out a doubt.
