The dyno I use is an older Stuska and the computer doesn't control the sweep. It would be hard to plot that.

If we look at extremes though, I would mention one of Jon Kaase's 820 cube mountain motor pro stock engines. They use an aluminum rod, but they are still 720g, with a piston that's about 4.780" in diameter, and a stroke of 5.750". These engines will peak at over 9000 rpm, and they are about as zippy as they come.

I could also mention a 351W out of a '74 LTD that is indeed a small block, but probably revs like a fat turd.

Now granted, a typical street/strip FE is not an 820 inch mountain motor with aluminum rods and a Sonny Bryant crank, but the same principles still apply, and they can be quite zippy....and still pull to a high rpm peak. Physics indeed apply, but the engines don't know what their rotating assemblies weigh.
