No-Quarter, the problem (if it is a problem) is, the Ford drive gear roll pin is physically smaller in dia. hence weaker in shear than the roll pins in old Chevys, which also use spur gears. GM spur-gear pumps pulse a lot but are very tolerant of debris in the oil. Gearotor pumps give a nearly pulse-less flow of oil, which is another reason why gearotor pumps are used in most dry-sump racing engines, and current Ford & GM engines since the mid-90s.
