engine size

how true is this statment when applied to our motors. This was written bt a bbc guy.

HP gain his not consistent as displacement (CI) increases therefore its not realistic to just use a simple equation like that. Take a conventional BBC for example, it's peak displacement for HP/CI would probably be in the 500-525ci range. It may be lucky to gain 1hp/ci as the displacement increases past that size but below that size it may increase at over 2hp per CI. So Lbs/CI

Smaller motors will tend to produce more power per CID..... However.... Bigger Engines of the same quality will make more power overall..... So pick your poison.

Generaly its cheaper to build the biggest engine possible to get more power than trying to make big power with a smaller engine.

Like Building a 429 vs a 557...........

I know small blocks won't produce the same torque as a big block but they make up for that by becoming high reving screamers, and they can produce more hp/cuin than most big blocks. They need less weight to be competitive with the big blocks
The mountain motor pro stocks are still faster than the 500 inch nhra pro stockers, so they must be doing that with huge torque and less horse power per cuin?
