how much ET did you pick-up with the ignition? I've added a Mallory Hyfire VI AL for the rev limiter and picked up nothing, no real difference in idle quality, but i still had the stock coil and distributor. I'll be installing a new 6 AL2 today with a built-in 2 step and have also installed an Accel Super HEI coil last races with new cap and rotor. No improvement on ET.
