In all honesty, I couldn't imaging why that would happen? GMs HEI has been on the street for years without any problems like that. You would want to use a good plug wire of course, nothing old or cheap. I plan on using an Accel high voltage street coil on mine which will be no different in ratings than the ignitions they use today or GMs old HEI system. Theres a Gent in Richmond MI just north of me that has been doing the same thing for years with his SM that he uses for both pulling and Farm duty without any concerns yet. Its no different than my old Chryslers running higher/modern ignition systems now, for years. If you want to use a coil that needs a Ballist resistor than do it, that surely wont hurt anything either, just depends on what the coil needs to see for voltage, and most old stock such as the Chryslers saw 8-9 volts at the coil, as thats what the coil is rated at, the starting bypass of 12 volts was for a boost when starting since over all voltage would drop while cranking.
