Re: Gear drive replacement for timing chain
I installed several while I was still wrenching, primarily in high-rpm race engines. The last one I did was for a friend who now has 3 years and about 20,000 on the engine. This was in a 8,000 rpm long-rod solid-roller 302, and it was a Pete Jackson "quiet" model (though it wasn't exactly quiet). I don't remember what my friend paid for it, but he said he bought it from Summit Racing (I think they're around $125). We primarily used gear drives in high-rpm big-Hp engines for their more accurate cam timing and strength, on lower rpm engines (below 7,000) we usually just used a Cloyes 'true-roller' double-roller chain.
