A question of dwell

   Did you not get the instructions with the Pertronix? The red power wire should go to a switched power wire. You can attach the red wire to the positive side of the coil, black to negative. If you have a ballast resistor (most sixes don't) attach  the red wire to the end of the resistor that comes from the wiring harness, not the coil end. 

70s cars usually have a resistance wire instead of a ballast resistor. In that case you need to find a wire that supplies 12V with the switch in the crank and the run positions, or find the resistance wire in the harness and splice in front of the wire.

	I didn't buy the Pertronix. See my previous post.
