Dot Heton,
It's a great discussion. There is nothing magical about what the engineers and gang did with these motors - this is what engine builders and engineers do. Computers allow us to quickly calculate and plot out these things.
Because it might come up, the total area for Piston CFM demand for each is as follows:
136mm rod: 30813.1cfm @ 28"
145mm rod: 30812.8cfm @ 28"
This is a for a 75mm bore x 74mm stroke @ 7200rpm.
