If the power level goal is 2.50 HP/cu.in, at the same efficiency (MEP) a larger engine would need the same RPM.

In theory, its more difficult to obtain the same efficiency with larger displacement.
If less efficient, then you would need to spin to a higher RPM.

Gives insight as to how challenging it really is!!!
