Two cylinder heads, all else equal, the smaller MCA(and we are talking within reason...not to any extremes like a 2")should, according to the definition you stated earlier, make more power...




this is based on your conclusion on how velocity operates in a port,, maybe based on you thinking its like a flow bench and the port is "on",, not in a running engine that has "velocity" of the charge as dictated by the piston speed/depression created in the intake stroke,, there is no vaccum in the compression stroke to generate velocity,, it is created by the residual charge in the port upon sweeping the intake stroke,, which we call inertia,, which impacts the cylinder as the piston is comming up,, the smaller the window it has to flow through,, the less of an impact it has AT HIGHER SPEEDS

a side note,, in drag racing,, "we" try to make power at higher speeds,, to get down a 1/4 mile track faster and quicker
