For that set up, we normally choose a stock cam. It produces a better idle, and has a broad power band for "everyday" driving. Stock Ford cams are well hardened, which is more than we can say about aftermarket shafts, which have shown a tendency for rapid wear. If you go to a higher lift, be sure that there is sufficient room in the heads. We install larger intake valves, usually Chevy, which helps the breathing.

Brad, another thing to consider is that the lower zinc content in the engine oils available today do not present an issue with a stock ford camshaft. Alan
