I have a converted chevy distributor in my 8BA. After 3-4 thousand miles the contacts look rough. I filed/reset them and it's running good again. Wondering why they didn't last, I went to looking for the reason. I have a 1.8 ohm ballast feeding a flame Thrower 1.5 ohm coil. On a 12V system I have 5V at the coil, key on, points closed. Running I have 11 volts on the input to the coil and 8.2V on the distributor terminal of the coil with the alternator charging at 14.4 volts. Reading comments on this forum directed at 6v systems, I see 4v is recommended. I've Googled a good bit and can't find any info on voltage to the points. I'm looking for help to determine if I need more resistance, or if I just have crappy points. The ones in the distributor are Delco. Thanks for your guidance.
