? about that 3.65” crank

I agree, if an engine turns more RPM it will have more combustion events or 'power cycles' per second than a slower engine. It has to. And I guess an engine with a shorter stroke can spin faster (though that is not a given). I don't like the term 'power cycle' as cycle tends to imply the 4 strokes of a 4 stroke engine and at 3000RPM, an engine has the same number of power cycles per second (or minute) regardless of stroke. The statement as it is written above "The shorter stroke will have more cycles (suck, squeeze, bang, blow..) per second" is just not correct if you make the reasonable assumption that 'per second' is tied to engine speed, i.e. RPM. That's why speed measurement of any sort includes a time reference. You can't say a clock with a shorter second hand goes around more times per second than a clock with a longer hand.

The presumption is a Pro Stock engine has the biggest bore possible is based in a lot of things....power cycles might be one reason but so are other factors like less valve shrouding and there is not that much need for low end power in a big engine/light car that can be revved high off the line. So what's really being said is (for example) 10,000RPM of weaker combustion events is better than 9,000RPM of stronger events...because the shorter stroke will produce less power per cycle (assuming the engines are both optionally tuned).

I've talked to a few guys who, right or wrong, tell me the R5P7 engines are not as popular in door slammer type drag cars because they make tons of power up high but suffer on power down low. In a NASCAR race no one needs low end because they don't spend much time under 6000RPM , but in a 3000lbs drag car what happens from 3000RPM and up matters more.
