Guys, I need some input. Getting the points set just right on this thing is causing me to rethink the whole idea of maintaining it's originality, especially if it's not noticeable. So, I'm looking long & hard at converting over. Been looking at a Pertronix system. Haven't really researched any other brands. Am I making a mistake in going this route? Something better out there? Thanks all.

Done about 6 of these Pertronix conversions 6 and 12v in my shop.  So far no issues.  Make sure to use the correct coil.

Joe Jensen

I put the Pertronix ignition on my '49 about 2 years ago.  No issues so far.  However, I do carry the points system in the trunk just in case.

Good luck!

Pertonix on '47 and '58 for ten years.  Like a rebirth, better starting, acceleration, etc. Also installed it on a 1936 other make with dual points.  A revelation!

Just be sure you get the full 12v out there instead of the spun down voltage.
I had a petronix in our 70. Removed it when trying to troubleshoot a problem and never put it back. Our 55 has points.

Running points in my '53 the last 20 years, I just put in a fresh set (nos) with new plugs after a long sleep over the dampanic. Set them to specs, and after getting it started, check with dwell meter and make final adjustments to 30 degrees. Fergitaboudit.
I do have pertronics in my tri-power 327 Chebby, very tight quarters for maintenance there because of the rear carb. No probs with it so far.
I think correct coil as mentioned is worth consideration.

Personally, I prefer points in my 1949 331.  They let you know when they are wearing out, I can buy NOS Delco points on ebay and I buy brand new correct condensers from the Madison Tractor Co.  The motor runs perfectly.

I have installed several Pertronix systems, never a failure, they have worked well for me.   Will probably put a Pertronix II in my Bonneville soon.

Installed them in my '56 back in 2020 and no issues so far. I also installed the recommended coil for this product. Clay/Lexi

Installed in my 57 10 years ago. No problems.

Don't do it!! I tried it at the suggestion of others on my '59 — and the pertronix went out on me a couple months after install on a hot day. I swapped back out to points and never looked back. Starts fine, runs well. These cars were designed well and you should maintain the originality of it...with the original components. Not a fan of pertronix at all. As far as I'm concerned, not necessary. Good luck.

I have a restored '55 CDV, all stock 331 with Pertronix and correct coil. NO PROBLEMS!!
Also have all new wiring harness with a Powergen alternator so I know the central nervous system is fully functional.
I HIGHLY recommend Pertronix but DON'T DO half the job, put the correct coil in and make sure you have wiring in perfect condition.

Well thanks guys. As with most things, it seems like there are pro & cons. Guess I'm just getting tired leaning over that fender, trying to get the point gap set just right. Who in the heck puts a distributor buried behind the engine, and no little window to adjust the points? Geesh.......

Yeah, what mad man decided to hide the distributor way back there? At least I had the adjustment window on mine so your car must be '55 or earlier. That is a real pain especially as one gets older. That is why I changed mine. Clay/Lexi

TJ Hopland

Did anyone else have the window or was that just GM V8's 55-74?  Oddly I don't think I have ever owned one of those, mine seemed to be inlines where they didn't give you the window.

OK, I'll bite. How do you know when points are wearing out? I don't know.....

The motor will start missing and, in general, run poorly and less powerfully. What happens is that over time the contact surfaces of the points become pitted.

The window in the distributor (and a different points set) was introduced in '56.

Plus, the window was put there so that the points gap could be set when the engine was running, hence the Dwell Measurement.

Prior to the Window, the points gap was adjusted using a feeler gauge.
