Re: [Chrysler300] Pointless

Contact Philbin Distributors in Portland, Oregon. They can answer all your questions, rebuild your vacuum advance diaphragm operation, and give you correct coil information for your engine using Pertronix Ignitor. For the C you need a 1.5 Ohm coil. I just got a spare NOS 300C distributor gone over by them and had a Pertronix Ignitor installed. I have been running a Pertronix on my current distributor (no pun intended) for 11 years now. Hope this helps! 300’ly, Rob Kern

It would be helpful if someone in the know would answer these questions:
What is the difference between Pertronics I, II and III?
Which is most appropriate for our 413's (with & without rams)?
Is it necessary or advisable to replace the coil?
If so, is there a specification for the new coil?
Is the start/run configuration including the ballast resistor retained or modified?
Is the vacuum advance retained?
Is it advisable to carry a spare?
Is there a Pertronics wiring diagram available online?

Separate issue: Can vacuum advance cans be rebuilt? If so, who does it?

I have no idea if the Ebay sample is of good quality, but my recent experiences with Pertronix units suggest to me that it's an excellent conversion if your distributor is in good condition. The unit enables you to retain all of the original appearance except that there will be 2 wires from the coil to the distributor instead of only one.
In the past I've heard of some reliability issues with those for some applications, but I believe that those problems (if they existed) have been appropriately addressed.
In any case I do recommend that you replace the vacuum advance diaphragm if it is more than 8 years old. It's not a lot of fun to dig deep enough to do distributor work on most of our 300s. I converted my '55 12 years ago (also a 12volt electrical conversion) using a MOPAR conventional electronic system that included a distributor from a 318 engine (slightly modified for hemi instal), an added ballast resistor, and the ignition electronic control unit all removed from a 70s vintage Dodge pickup. It has been trouble-free for me for 30k miles, but because of the simplicity of the Pertronix system that is what I would use if I were doing the conversion today.
