I had a 350c1 in a Vette, it was making a knocking sound up front, I replaced the alternator, still there, I replaced the water pump,still there, I finally tightned the balancer bolt and fixed it. On my race car the balancer fell of, after ruining the crank. Everybody go check yours now!  Bill 1362
