Well my old 446 was a .030 over 440 with 906 heads and the MP .557 cam. It use a Holley Street Dominator intake and a 850 DP and was 10.0 comp. Ran fine on pump gas as I used the KB quench pad pistons to get quench. It also used 1-3/4 headers. I never dynoed it but it ran a best of 11.49 @ 116 in my 3700 lb 63. I would guess it was about 500 flywheel hp. Ron
