I tore apart a Predator 459 to see what all the hype was about
This engine created a lot of buzz because of the oil pump and the large size
This a good engine for industrial use when the governor is intact

Only the aftermarket cam fit this engine. The ARC billet rod and flywheel do not fit this engine…and I never run an ungoverned engine without those parts

The crank does not use roller bearings on the crank and no positive lubrication for the connecting rod
