I thought I'd ask the question here since the flywheel is from RF. The damper is from Ford for a 96 302 using a crank trigger, as above, the flywheel from RF. To my untrained eye, the flywheel looks to be zero balanced. That is what my engine guru said also. Now the damper looks to be not zero balanced. So...I get a machine shop to zero balance the damper, right? Any help would be greatly appreciated!
