Plug gap is .035"; Point gap is .020; Dwell is 40-45; Valve clearence is .010 intake and .020 exhaust; Timing is whatever you can get away with in today's world. I'd start at 5 degrees BTDC and tweak it from there based on mileage and performance. Originally it was 2 1/2 BTDC but that isn't enough. Idle speed is 550 RPM.
