Am I the only 1 thinking that the sum of the parts would be around 550-575HP on gas?
And no you're not.
Remember the engine master shootout with 440s where, I believe it was Hughes, built a 750hp deal? They moved the cylinders around and other super tricks, With Indy(?) heads? They were running gas, but still,,,
This motor really put a # up! Good job Bill/Koffels.
