What would it take to make 1.44 lbs-ft per cid ?

If you look at what port size cc is needed for a given cfm to make a velocity of 260 fps are roughly.

225 cfms = 170 cc, 250 cfms = 190 cc, 275 cfms = 205 cc, 300 cfms = 225 cc, 325 cfms = 245 cc.

If 260 fps is the ideal for best balance of torque and hp. Supposedly above 320 fps hurts hp below 240 fps hurts torque. If correct it seems like we generally don't have enough port for a given amount of cfm.
