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

Who says so? Not the thread title.
It was the point, basically what would it take to make a 365 (NA) have similar power and torque at similar rpms as the 408 in the dyno graph in post 1#. Was trying to figure out some of the design criteria when trying to build high torque per cid over the more normal 1.15-1.29 lbs-ft per cid the average guy gets.
