Quick dumb question...curious lol
What causes that crackle kind of idle? Is it the actual cam itself plus the kind of exhaust? I'm guessing it has something to do with duration? Or overlap? Almost sounds like marbles coming out the exhaust lol..just think it's sounds bad ***

"More overlap makes a choppy idle and tends to make peakier power for the same reason as a narrow LSA does. More overlap and the subsequent lower intake manifold vacuum might mean giving up vacuum-driven accessories like power brakes."

Going to stick with the same mgs.Compression ratio dictates what cam should be chosen.
Any cam chosen for the "sound of it",is a poser cam used by a poser end user.Hate that!!.
