Find a used Mallory digital 6 box, number 685 and buy the correct coil for it and be done. It will run forever.

I have several on the shelf but none for sale. I buy all I can at swap meets for pennies on the dollar. Bought an analog 7 box with coil, a two step and two stage retard for 80 bucks. Already tested good.

80 bucks because it didn't say MSD. All the better for me.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
