I know this isn't completely on topic, but here goes anyway.
In every instance I've increased the volume under every mopar head I've tried (primary limiting factor) I've gone faster. From -1s to predator, stock hemi head to millennium. The heads have been over faced with job in almost every attempt, yet inches alway resulted in speed. Even when the efficiency was apparently less.
Let PS have 501 CI , or 600 withe the same induction, and they'll go faster too.
This is right on, you never ever will see a NASCAR run 300 CID because it makes "more pulses per minute" and all the other theoretically sound technical explanations, you will never see a formula 1 run smaller than the MAX, never see a 400 CID pro stock when 500 is the max (assuming both engines can use the same induction and no rules to favor the smaller CID like weight breaks) you just plain go faster with more cubes, the 73 340 is slower than the 74 360 with same heads, cam, carb, exhaust...
