Great product went right on beware there is two keyways if you install in wrong position your going to take it back off and spin balancer 180 degrees. Engine did not fire up on first position. Balancer seems to be slightly heavier than stock. I have stock blower pulley but cold air intake and i can hear the blower working more now plus I feel more acceleration. And you must use oil neck spacer for clearance. And I suggest getting the higher oil pressure relief valve while your there. Because I sure regret not getting it. ZZP you did it again!

Good quality balancer , pulleys pretty much stock grade nothing special, cured my belt slip 2.8 pulley NIC cam
