Re: Bronze Or Hardened Distributer Gear ?
Bronze is a sacrificial gear for billet steel cams, the gear may live 5k on the street, and is designed to wear away before doing damage to the billit cam.
Hydraulic roller vcams use a regular type cam gear coted with a "Melonized" coating for break in, and stock GM hyd roller cams are industrial hard chromed from the factory.
The new disaster composite cam gears are supposedly for other than cast cams, to help with increased mileage, before they need replacement. I see a lot of these, absolutely done in in less than 4K miles.
Plastic gears are useless, 10K and they are work heated enough to crack and fail. My Plymouth 225 Slant 6 went through these stock plastic gears right on target, 5K miles, cracked, split, done in.
There are also both hardenable, and hardened cams available, they require different gears as well.
