I remember Keith C. was pretty opposed to the shorter stroke idea. IIRC, he went so far as to say it was "dumb" to run the shorter stroke crank (4.125") in an FE so that it would rev faster. That was in response to something that Barry R. had said supporting the notion. Neither one of them built my engine. I think you could line up as many smart FE builders as you want on either side of the issue. One thing I really like about my engine, that has nothing to do with its performance, is that, with it not in gear, I can tap the throttle at idle and, instead of it "revving up," it will just go
"blam" and instantly be at four grand without having gone through 2k, 2.5k, 3k, 3.5k -- mucho funno to do.
It doesn't rev, it explodes.
