Putting higher RPM on a 3 gives it the same pulses per minute that a 4 has. They are fine. If modern in the sense that they have electronic fuel injection (diesel or gas) and electronic ignition and engine management, those are superior in performance for those reasons alone.

It is free displacement in the sense that it pumps more air, and makes resulting power. The wear factor is not important, it is usually not twice the RPM. Jim [Reply]  [No Email]
