When planning on a cam, its good to match it with your current mods, or if you're planning on a specific mod for the future (like F.I.). I always like a custom grind, but you either need to already know what you want for specs, or talk to an experienced custom cam maker. The Ford Letter cams can sound good, but they can't beat a custom cam.
