    Dead cylinder? Bad connecting rod? Does the cylinder get a spark? Are the valves opening & closing on that cylinder? Is the connecting rod bent or the bearing scored? Sometimes a "mechanic" will replace an engine rather than repair the immediate problem. Consider the mileage, the overall condition of a 44 yr old vehicle, & your time & budget. Don't get double-talked into replacing an original engine and lowering the value of an historic vehicle.
