MY 1968 had a very poor overhual done on it over the summer where the cam, lifters, fuel pump and oil pump were re-done. The local hotrod shop who did the work could never get the lifters quiet. I've since have had it looked at by someone else and they couldn't either? The motor has less then a 1000 miles on it. (Engine, Pontiac 350).
Any suggestions to quiet this sewing machine down?
