ignition timing? 5.0L
running a chip and premium fuel+additive, i have it set at 20 degrees before TDC... would this hurt? i run only premium with additive in it and it doesn't detonate or make that ping. it actually runs better, more throttle response, reaches higher rpm's(10 deg. b4 tdc 4700 rpm, 20 deg. b4 tdc 5000 rpm), has more all around power... wouldn't hurt right? lol plan on swapping out for a built 302 thats in the works anyways... the only noise i hear is the #7 cylinder's valves tap(high mileage truck)
