Rick Lakefxbill The gear you are talking about is made by Greg Depree. 803-730-7574. As long as you are not a nascar builder, he will sell you one for $80.00. He makes them for comp cams. They are the gears they use in the nascar motors ford and that other makes. 3 thing are causing gears to wear out, no or poor oiling to the 2 gears where they meet. Too much end play on the camshaft, causing the gears to rub again each other. The distributor shaft not being square with the block and cam gear. A high pressure, high volume
oil pump will help wear out the gear but not in 5k miles. You need more than
oil splash to keep those gears with proper lube. There is a trick to put a .030 groove in the lower distrib housing so the
oil pours onto where the gears meet. The gears are not plastic, they are a polymer with carbon for strenght. The more carbon the strong the gear but the gear gets brittle also. I think that a geo gear pump like titan has less drag than a gear to gear pump. A titan pump is $700.00. For this knid of money I would go with an external oil pump setup that works off the crank. Avivaid makes a kit for FE motors. More volume and pressure, and will not wear put a distributor gear. My thoughts
