When I compare my combo to others I check the ratio between cu in and the factored HP rating. My ratio is 0.90 HP per Cu In. Some in my same class are rated at 0.75 hp per cu in. So there is no way I can compete with that. My combo is a flat top with a q jet. Given that the 632 should have at least a 570 hp rating. Now remember that engine probably has a very high compression ratio and CNC ported heads. So it might need to be a bit higher than a 0.90 ratio.
