    Rated 1 out of 5 by from Not a high performance pulley I mounted this pulley onto the balancer and noted: pulley does not center by the mounting bolt holes, no index pin to center pulley, and will probably throw the engine out of high RPM balance. This pulley was intended to drive an alternator on my race engine.
