Ballast resistor Q's

Correct we don't know, but even with a mopar electronic ignition and say a msd blaster coil wouldn't the ballast have no purpose ? I always thought the ballast protected the older low voltage coils and points.

100% wrong!!Don't confuse using an MSD coil with using their ign. system.The
blaster series coils actually have a LOWER primary winding resistance, and a much
HIGHER current demand,generating even more heat than the OEM unit.The factory
Electronic Ign. still needs a ballast,and the transistor kept cool as poss.,it is not a
computerized ign. or a "discharge" type ign. as I explained above.
