[..My engine builder went the reliable as the shop truck route on the cam with the same size engine as mine, 10:1 compression instead of my 11.6:1 and stock flowing heads, vs. my 400cfm heads, and he is right at 657hp at 484 cubes.



more good info.

So 426/484 = .88 x 657 = 578hp out of a similarly built 426 (a little simplistic, but close enough).....makes perfect sense to me.
