I would love to find out the horsepower and torque curve all of this combination. I guess it will be something I will really never know. Although the Machinist I am bringing my block 2 as a Dino.
The example he has in his book are big block Chevys (BB MOPAR would be similar) is he runs 106 LSA and he gets questions on that choice when most are running 112-114. The ratio of valve to cubes per cylinder in BB are such that you can run 106 and have it run and idle fine and make better power across the band than a 112 LSA, according to him.
His method is based on his experience and realizing the LSA is selected based on the ratio of how much air a cylinder can hold (engine size) and the amount of air that is available to charge it (valve size). With an assumption of how well the head can flow. His graphs assume a “normal” type head. A known poor head would reduce flow and tend to tweak the LSA up and a great head would flow more tweak the number down.
