Minor question, but do "Ford" style gerotor gears move more oil than the MoPar usual kind? If you notice, the Milodon badass billet pump uses thinner but slightly larger diameter gears that they call "Ford" gears. These gears are more "spikey" instead of shorter/fatter rounded Chrysler gears. They used to claim less HP loss and more volume than a M-63HV, which I am fond of, with their external pickup systems. I saw a TRW oil pump gear kit for a regular-volume M-63 or OEM pump WITH the Ford style gears. Being the same thickness and diameter, I'm wondering if it would move more oil than the Chrysler gears do in a stock housing. Maybe with less HP loss than a HV? I like HV pumps with wide bearing clearances and thin oil (10w-30 etc.), and especially for a street engine with 1/2 or 3/4 grooved mains and internal oil pickup routing, this might be the trick. Anybody have any facts about the gear efficiency? Opinions? Thanks
