Truth about roller cams.... BEFORE you make the switch......

or chose one of dave hughes hyd flat tappet cams. they spec out amazingly similar to many roller cams and you don't have to carry the weight of a roller lifter and the requisite heavier spring to control it. I find that heavy springs wear cam bearings and valvetrain components / timing chains etc. We all know how to break in cams and the cost and simplicity cannot be ooverlooked.
