It's not the coil that reqiures the ballast resistor, it's the points in the
distibutor that triggers the coil.
Running at 12 volts constantly would burn out the points over time. Therefore
the ballast resistor is bypasssed during cranking, but the reduces the voltage
to 6V while running. The only way to run a full 12V is to switch to an
electronic ignition with a magnetic or optical trigger ala Gary Boone's
distibutor, petronix, crane xr700 or 3000, mallory, or ther
points-to-electronic conversion kits. Gary Boone's is probably plug and play
with minimal wiring involved. The others require taking your distributor
apart and changeing internal parts.

Subject: ignition coil
question - i'm redoing an early 67 low windshield 1600, and am seriously
considering redoing the wiring, by myself.
my question - there is a resisitor/ballast, which from what i understand
lowers the voltage? to the ignition coil. can you get a "better" ignition
coil, which then won't require the resistor/ballast? how does this affect the
distributor, the spark plugs, etc, all the stuff that follows?
sorry - this electricity stuff is not something i know much about . . . .
