I still say it is an ignition problem and compression and leak down should be non-issues. I may be wrong but i am going for the walking cam shaft theory because of a possible broken or weak plunger spring as others have suggested. No way to trouble shoot that without pulling the front cover that i know of. If you know of a way let me know as i have just jacked the car and do not relish going the rest of the way. Changing parts was a double check. I did find a distributor bad that a friend loaned me that he had timed and under his back seat for emergency road repair. He is glad we found it now rather than when or if needed. There was another thread on this titled "fixed till broke"

john did not mean to upset you you changed the dist> and coil to no avail,yes it has tappets we call them lifters today.i would want to know the compression and if the cylinders will hold in a leak down test,nothing to take apart and all to gain.i think you said problem gradually worse not all of a sudden,possibly rebuilder left out the plunger spring? Best of luck hang in there you will find the problem.
