The key to it is good machine work with a straight round cylinder, good ring seal and then good flowing heads. I feel that the Edelbrock Performer RPM is the right intake for the application and a camshaft with about 244/252 at .050 and about .620 lift on a 110 lobe seperation would work great in the real world. The Holley 750 should be about right and they have a 750HP with vacume secondaries that we have some real good luck with. I also wonder if the desk top dyno takes into account the fact that the camshaft gets smaller than advertised when the lash is set. I would think with a solid roller and a good set if iron heads with the 2.09 and 1.66 valves that you could get on the 500 to 525 range. Good luck, Keith Craft
