Finally figured out the Pertronix/Crane CD ignition interface. Yes, Crane is very similar to MSD. So thanks to the person who helped me on my earlier post. Car has been undergoing some extensive work, which is getting closer to being complete, but will of course never be totally completed. Smoked like crazy at first as I had squirted some oil in the cylinders the day before and cranked over by hand & starter motor. I think there may be something to these Crane and MSD ignitions. Those plugs had to of been oily as hell and that thing fired right up. I was shocked!
