  1. It’s not a production line but an engineering assembly area. When i put together vehicles for tests we hand torqued the parts for an ideal situation which proved the engineering worked even though it didn’t eliminate production line errors.
    They are putting together Chevy engines pre-1963 since the provision for the road draft tube is in the engine which was eliminated with Positive Crankcase Valves (PVC’s).
