The MSD Digital 6 Plus, PN 6520 and the HVC II Coil, PN 8253
The distributor is one that Accel custom made for Ford Racing. It is a being run as a magnetic pick up, and is fully adjustable. I am installing a MSD 6 Digital Plus box with a MSD HVC II coil. This combination puts out 48,000 volts, at 1 amp. That is a hotter spark than most magnitos put out.
The MSD 6 Digital Plus has 2 RPM limiters, a Start Retard, and a high rpm Step Retard. I will set the high limiter at 6,500 RPMs, and the low limiter to just below where the rear tires start to move under full power braking. With the 3,500 RPM stall speed, it should be fairly high. I will have to play with it some to see. The low RPM limiter is activated by applying 12 volts to the blue wire. I will start off using the 12 volts going to the brake lights to activate it. Latter when I put a line lock on it, I will tie it to the line lock circuit.
