Reply to "Distributor & Drive Gear"

The blank that is used to grind the lobes on determines the gear you can use. Mine is ground by Comp Cams on a -9 core, billet steel, which requires a bronze gear. The info should be on the cam card.
I checked my bronze gear at ~2,000 miles and I saw no wear. I intend to check again when I put the car back on the road in the spring. Using a timing light, my timing has not changed.
I had posted in one of the 351c forums if anyone was using the composite gears, no joy. In searches I think I found all Chevrolet's, some with mixed results. I bought a spare bronze gear which I keep in the car.
Great to hear you have had no issues with your composite gears.
How many miles have you got on them?
