Building a 383 help

@273 said above;
"Bottom end stroke rod ratio and displacement decides where the power band is."

Incorrect, cam duration and the ability to control the valves, AKA, valve springs and a few other factors do.

I do think you were meaning to say/imply that a shorter stroke likes to rev higher than a longer stroke engine which tends to make its power quicker in the rpm scale?

Like a 340 vs 360 or 383 vs 440 deal?
