How does cid make power?

I meant ALL things being equal, for lack of better wording, 3x the Cid + 3x the heads + 3x the cam.... 3x the airflow... etc

If you 3x the rpm with 3x airflow same thing, airflow the key component short block is just got to be able to handle it, same hp larger engine trades rpm for torque compared to smaller.
