Correct internal or external coil for pertronix points eliminater

Mike 69,
The voltage mentioned in post #11 refers to the secondary voltage. As best as I can recall, Pert did not differentiate between pri & sec voltage in their quote, but they meant sec voltage because the suckers fall for the big numbers [ 60,000v is better than 30,000 v, right ].
The sec voltage is governed by pri voltage & turns ratio. Since this kit does not change the pri voltage to any noticeable amount, there will be no increase in sec voltage. That was my point.
