I'll choose an engine that makes BIG POWER from 3000 RPM to 5000 RPM.
Still power.
Power is made from 3 things.
1 Displacement
2 RPM / piston speed.
3 efficiency - BMEP.
Efficiency is very limited. Fuel says compression can only be so high.
When RPM is limited that leaves BIG displacement / engine size to increase power there.
Using mean piston speed.
horsepower = (BMEP * engine total bore area * MPS) / 132000
Woks at only 1500 RPM or 10000 RPM. Let pick a well designed 600 cube engine for your example, will be hard to beat.
