Rebuttal of the "Less Stroke/Cubes=Rev Faster" Argument

Also, I think Jay is making a much more global point, not just limited to his 585ci SOHC engine.

Just my opinion, but I think the everyday Joe or Jane Six-Pack is kidding him or herself, if they say they can feel the engine with the 4.125" stroke revving faster than the one with the 4.25" stroke.

I call BS on most. Jay has built plenty of non-SOHC engines too.

I think that's pretty accurate. I have the shorter stroke 4.125" crank. I can't hit WOT much at all, and when I do, only for very brief durations and being extra careful to avoid wheelspin. It hits red line awfully fast, even on half throttle. I don't think another 35 cubic inches would make much of a difference one way or another -- and I doubt I would notice it anyway. Mostly, when I'm driving I'm usually wondering what's trying to rattle itself loose and leave me stranded out in the middle of nowhere.
