What would it take to make 1.44 lbs-ft per cid ?
It does cover a wide range 240-320 fps, If you calculate that out to port cc size for 300 cfm that's about 245-180 cc which is a pretty big range, and Trick Flows are 190 cc putting the on the small side and fairly high velocities 308 fps. If these are correct seems like not enough port cc is generally more of a problem.
Further ahead than I was before, think I got a few bits of good info to build on.
Air flow and it's speed (velocity) obviously plays a big role. But if you look at the acceptable velocities

That definitely play a role at particular rpms.
When you calculate a lot of these engines aspects out you see a lot of symmetries.
They tend to make torque.
