Rev the engine & listen for hissing noise out the tail pipe. Some of those old trucks had a double layer exhaust pipe. The inside could colasp & still look good on the outside. The compression is Ok being above the specks. Various models have different comp.ratios. Carbon in the cyls. can raise it. Could the air cleaner be plugged up?
