Assuming it has a flat tappet, non roller lifter, cam and lifters I'll guess a little over 700 HP, maybe 750 HP, at 6500 RPM and almost identical torque on 91 octane non ethanol rump swill luck
What brand an part number is your EFI throttle body?
I'm in the middle of planning a new race motor (551 C.I. B1-MC heads) with a crank driven centrifugal super charger with EFI running E85 pump swill luck
Hoping for 2000 + HP depending on how much boost I limit it to planning on under 30 lbs. at 7500 RPM luck
