Has anyone else had a problem with high volume oil pumps having too much pressure say 80 psi cold and 50 psi when hot? Already chewed up 2 dist gears in first 500 miles since complete overhaul. the pump is for a cleveland. melling m84ahv. The cam is hydraulic. so there's no material incompatability. The gear on the cam is in near perfect shape. just a small amount ofwear through the Parkerizing but no loss of material. I've measured the pedestal I.D. where the dist connects to the oil pump driveshaft and there's about .003 in. on either side of dist shaft assuming that the distributor and block are concentric to each other. maybe the Crane cam is made of a better cast iron than the distributor gear. I know that ford racing offers a "green" cast iron gear but I haven't found any info relating to their gear. anyone ever used one of these?
