blaktopr you bring up the same points I have in many of these discussions where smaller is automatically assumed to have better velocity and quality just based on port size alone. Even using the same head different porters are going to have different size and shape ports to get the same airflow, but as the Pro Stock guys(and the recent article on Chevy head testing I mentioned) found they may have varied power with similar flow due to those other factors. As you have stated it is just not that simple.
"the size, the shape, the flow??? MMMMMMMMMMM. How bout a question, can a 250cc intake port have the same velocity as a 175cc intake port. How and why?" Shape and entrance into the chamber are definite possibilities.
I've been called ignorant for suggesting that port cc is not the end all factor.You might get the same label for questioning that.
