Um....actually, it has ALOT to do with torque. Horsepower is calculated from Torque produced at a specific RPM, being as Power is Work per unit time (time, RPM -- revolutions per minute). If an engine loses its breathing ability at high RPMS(like the 4.3's do), the torque drops and so does the HP.

Correct ..... AND small motors don't produce much torque but rely on RPM to obtain their HP #'s. Which takes longer to build compaired to some nice large Detroit iron. And of course it all matters on how well the air pump can breath.
