How does cid make power?

Why is that a bad example? Why do you have to use similar architecture? The example shows why a bigger stroke gives more torque,and therefore more horsepower at a given rpm.
Would a comparably built 302 versus a 383 be a better example for you? I guarantee the 383 wins.....

383 what? A 302 will make as power as a 383, it will just do it at a higher RPM. No magic there.

Comparing a small block 383 to a big block 383 is a bad comparison. Only people who have to say CID and/or torque does it all make that argument.

Bore spacing is HUGE deal.
