HP = (TORQUE * RPM) / 5252

Longer stroke engines make more torque, shorter stroke engines make more RPM. Both Torque and RPM make HorsePower. Builders are always looking for the best blend of both for their application. Drag racers may want longer stroke engines while road racers may want an engine that can go all day at high RPM.

Adding stroke without increasing the deck height has its own set of problems. I'll leave that for the engine guys out there.

It's all a compromise.
