Power is limited by fuel delivery rate. The amount of power the engine actually puts out after frictional losses will be greatest at a lower rpm for a given constant fuel delivery rate. This is because the frictional losses increase with the square of the speed while the power increases linearly with increasing engine speed (rpm) with a given amount of torque.

Therefore, if you can get enough air in per stroke to burn the maximum fuel delivery rate then you will make more power at a lower rpm while also making more torque for the same reasons of friction's relation to engine speed.
