I will be starting my rebuilt engine soon but am unsure what cam sensor gear to use. The Comp Cam roller cam is supposed to tear up the stock gear. I bought an import brass gear but it looks too soft and I don't think it would last very long. Comp Cams makes a composite gear. Which one will it live long term. I'm not crazy about any of them breaking down and filling the engine with metal particles. Been there, done that with a flat cam. What's the deal? It there one I can install and forget about for 20K miles on a street car?
