If you read the last line I guess Im on the right track
(1) Drill a .030" hole in the lifter/
oil galley plug behind the distributor. This will allow additional lubrication on the distributor and cam gears. This will not lower
oil pressure enough to hurt the engine.
(2) Ford
oil pump mounting brackets have elongated holes. Due to this, the distributor shaft and oil pump shaft should be aligned so that the distributor turns freely before tightening the mounting bracket bolts. Failure to do this will cause a binding situation, thus damaging the gear.
(3) Stock Ford hex oil pump drive shafts are know to vary in length which could cause a bottoming or binding situation.
(4) Brass distributor gears can be used to avoid damaging the cam gear. Brass gears are softer and can wear out quicker than the cast gear, but will not cause damage to the cam gear. If using a brass gear, check it occasionally for wear.
