I hope CBN89 can answer this question for you. If you are staying with the OEM plugs, points and coil ignition system there are limits on how much modern you can add to your system. So, I will not get into the details. CB 89 is so much better at explaining the role of the ballast resister and the correct spark wire for your system. Something that many person do not understand is the difference between a hot and cold sparkplug. This Information is available on the internet and Googling for the information is easy.
I was reading the details of the TEC3r system I installed on my 1947 Ford Flathead V8. Even though this system can, where and if required, produce a spark with up to 80.000 volts strong, the maximum spark is determined by the energy needed to jump the gap at the sparkplug. This could be well under 10,000 volts. I expect this might also apply to your system. The spark intensity is all about compression pressure against electrical pressure. A low compression engine will not need the spark intensity of a high compression engine. I suspect, but cannot say for sure, RPM will be part of the equation in determining spark requirements. I am thinking of the 4500 maximum RPM in an Old Ford or IHC versus a Formula One at 20,000 rpm.
I read a good article, on the internet, that suggested buying an expensive coil in the hope of getting a much more powerful spark may be money wasted if a regular coil can and will work just as well. The theory is the spark collapses once the gap is jumped. I will try to find this information and post a link.
I would rather have tools I do not need than to need tools I do not have
