My experiment with the MDS 6AL Digital Ignition control box, pairing it with the Pertronix II igniter that I already had in me 65 Coronet 500, have made a big difference with my TNT 440, both better idle and gas mileage. Along with my 323.1 sure Grip, it now burns the tires in first gear all the way down the street and 1/2 way in in second gear,,, and when on cruise control at 2700 RPM's it stays on the expressway at 70 mph all day long.
Not bad for a normal street car
,, why did I wait so long.
1965 S/S RB Coronet 500.
