Generally true about piston diameter, but longer stroke is problematic also. To minimize piston inertial cylinder loading you may need to increase connecting rod length. This also moves peak torque up the rpm range for higher horsepower peak.

I'm guessing Jake is building a shorter stroke, bigger bore engine to raise rpm level.
