Here's what Lynn just mentioned regarding velocity regarding a Pontiac Iron head with only 180ish cc
"The biggest positive in a race engine will be to keep the maximum flow velocity to 614 feet per second to minimize splitting the fuel out, and not choking down the intake charge.
My SS 455 engine calculates obout 769 fps in the push rod area. It seriously limits horsepower, RPM. "
So to much velocity is a bad thing also!
