Its where and how the power is made. The engines make all their power so high in the RPM range that the hydraulic valve train is the determining factor. The engines don't really start to pull until 6K RPM, and before that they often make less torque than a standard care engine.
The big ports and big cams, with the huge plenums make for an engine that has a narrow power band.
The same characteristics follow the engines, even when they are made larger.
