I can't find anything specific on this. I have Ma's electronic ignition on the 71 with a bone stock B motor (77 400 4bbl), single ballast (.8ohm and a 1.4 on hand), stock elec.distributor, 4 pin orange box and a 8140C coil. What is the correct resistor for this coil?? I was initially under the impression you could run straight 12V to it considering its a 12V unit but, it seems otherwise. I just have found nothing that specifies what ohm resistor should be ran. Appreciate any help
