Port Cross Section and Torque Peak RPM

While I'm sure some head guys will have those actual measurements for a Mopar combo, I don't and I'd wager not too many will want to share much in terms of that level of detail for free.
In terms of what you're reading... The port is the potential, the cam is the amount of potential that the engine will access. That's why the cam choice can be so critical. IMO basing the value or quality of a port strictly on the cross section is a real simplification, because size does matter, but not in the same vein as "bigger is best". I can, however understand why Andy might choose to keep it generic and word it that way. The torque curve is the empirical measurement of the cam's efficiency with the port. Not the port size with the displacement.
