I was going to suggest taking it apart to fix the compression but didn't think of it till now, but I got beat to it anyways.
Late 70's engines got real shady in order to meet "The Mans" emission requirements. CR's dropped off the face of the planet and they didn't go about it the right way either.
The pistons in my 1978 250ci Ford I6 are no less than A QUARTER OF AN INCH from the top of the deck. Yup, 1/4" of cylinder wall is showing.
But your engine might be different since it was for a truck and not a car.
