I use Pertronix 1382 (original version before II or III) with stock coil and jumper the ballast resistor to provide full 12 v.
To jump the ballast resistor either gut one and replace resistor with a solid wire and solder the terminals, or make up a short piece of wire and install the piggy-back (Molex 19043-0010 ) terminal to retain original ballast resistor.
