So, what were the actual #s you came up with using the above combination? If you posted them elsewhere, I never saw 'em.
Also, I'm "thinking out loud" when I wonder how close to 700 HP someone could get w/ a pump-gas friendly combination in the same general displacement (500" +/-) that still uses a solid flat-tappet cam. Oh, and bolting up a "real" exhaust system (3" w/ straight-through mufflers) shouldn't choke it to death, either...
