I would guess about 525hp. My 440 is 10.0 comp with 906 heads I ported myself. I use the MP .557 solid cam and a Holley Street Dominator intake with an 850 DP. My 440 make's about 500 hp going by the car weight and mph. I would think yours will make more hp then mine even though my cam has more duration as you have more comp and most likely better heads then me. Sounds like a nice combo. Ron
