F-BIRD'88 is right. With ASSUMPTIONS of 1.94"/1.5" valves but H.P. heads, large headers w/o cat, 9.5 C.R., hi flow dual plane intake with 750-800 CFM carb., and the XE274H cam, the numbers are 415 HP @5500 RPM and 460 LB-FT @ 2500RPM. This is doable. Source is Camquest(R).
I still worry about the rotating parts condition.
