HEI Ignition Coils
I'll just try to fill in the part I think he skipped, and he and others can correct as needed.
The voltage rise at the spark plug will depend on the local conditions. If conditions for conduction are poor, higher voltage is needed. My understanding is the spark duration and energy has coninues to have some relation to the combustion conditions around it as well as what is available from the coil after the spike.
Even with points, spark is goes out on its own.
My interpretation of the ringing is it represents left over energy which could have been used if needed to extend the spark. But that may not be correct.
Kit knows this stuff much better than I do.
