I'm going to say that if you took that 470, swapped out the pistons for some domes to get the cr in the 13.5-14:1 range, gas ported, skinny rings, vacuum pump, big cam....... Both the power and the peak rpm would go up.
what about more cube's,(512) moderate compression (12.5), vac pump and a cam just under .700 lift??
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
