Put 50lb weight on the end of a rope and spin it at 50rpm. Now put a 40lb weight and spin it at 100rpm. The 40lb weight WILL have a higher centrifugal, and gyroscopic effect. (same length ropes btw).

I understand this, but an engine (other than the crankshaft) continously changes direction up and down. You are not spinning something in one direction. The piston is at 0RPM at the top of the stoke and 0RPM at the bottom of the stroke (regardless of engine speed), though the acceleration is not 0.
