I have a wobbling crank pulley, i noticed it after i drove to north carolina, i was checking the motor before i made the trip home. I tried tightening the bolts ,but they were tight. It made the return trip , but now im worried, i might have bent the crank stub. I talked to the guys at the cruise tonight , and someone suggested that the stock balancer is coming apart, but it looks fine to me, any thoughts? Its a sbc, all stock.
