And it is a proform ignition system. It's not stock mopar ignition or a mplar performance kit, it's the slightly less expensive after market model. brand new made for mopar..
From what I can see, it works just like the Mopar system. Make sure the reluctor gap is set at .008" as per the instructions.
I would ask that you do this: Set it where it is idling stably, at as low an RPM as you can, and with the vacuum advance plugged. Look at your timing mark with a timing light and note it. Then stop the engine and line the crank mark right where the timing mark was seen with the light when it was idling. Then, without moving the crank, pull off the distributor cap, and look to see if one of the trigger teeth on the distributor shaft is point dead-on right at the reluctor gap. (Make sure you know what the reluctor gap is that you are looking for.)
This is a simple check to see if your reluctor phasing is reversed or OK.
