I'm all for eliminating points. I was making a living changing points and condensers every 10K miles when some of the "experts" who post here were still filling their Pampers, or possibly long before that. Using a Pertronix as a trigger is leaning on a weak reed, however. Both GM and Chrysler have 6 cylinder pickup coil and reluctor trigger systems that are far more reliable (and less expensive) than some fragile setup like Pertronix, plus those have close to 50 years of successful operation on millions of vehicles. Either trigger assembly is easily adaptable to the stovebolt distributor by anyone with some basic machining skills and enough of an open mind to try.

Now we can speak openly about mods that ARE NOT ORIGINAL. Thank you mods.

My experience with Pertronics since the late 80’s has been a good experience. Maybe their quality is slipping, don’t know. YesI know it’s possible to trigger coils in several different ways. But as stated, i want to use a stock appearing distributer. Too many heads would explode if I made a new side cover with LS coil mounts!

This is my tinkering and my fun. You’re welcome to your opinion, but I’m going to use the parts I have on hand for the first revision. Will it need refinement? Probably.

"Measure it with a micrometer- - - -mark it with chalk- - - - -cut it off with an ax!" Your choice of a trigger device is fundamentally flawed, unless you're willing to do some major internal modifications to the distributor itself. The manufacturing processes used to make an item that was meant to last maybe 10 years- - - - -60+ years ago- - - -don't lend themselves to working well with modern electronic components.

Since it's becoming painfully apparent that any advice I offer is going to be rejected, I'll back out of this discussion and leave you to repeat the same mistakes I made a few decades ago when I thought I knew everything. Good luck!

I used to be a big fan of Pertronix in my 235. The engine ran great, just like one does with a brand new set of points set at the exact point gap.
Then one morning I go out to start it up. No go. I opened the hood and saw that the top of the coil had melted and all of the oil drained out.
I checked to see if I had left the key on. Nope the key wasn't in the ignition. Problem is, the foreign made ignition switch I recently installed did not reach the off position completely before the key could be removed, allowing it to be on without the key in.
I bought a new coil and tried to start it. No go. Pertronix fried from the ignition being left on, but not before it melted the coil.

Moral of the story is that I consider myself to be very fortunate that my truck did not burn to the ground for something as simple as leaving the ignition on. Can the same thing happen with points? I don't know. It does not happen with HEI.

Would you mind explaining how a bad ignition switch is the fault of the Pertronics?
I’m sure HEI was great, in the 80’s......we’ve mored past that and 3D timing control based on rpm, tps and load make spark tuning so much more accurate.

I was just on the local craigslist site and saw an ad for a Pertronics distributor for $25. The guy said it had died within 4 months of install and got it warrantied by Pertronics, then the module died on that one withing another 2 months. He even still had the box. Kind of reinforces why the other guys are saying to avoid Pertronics.

Here’s a couple truisms of the internet
Whiners are the loudest
Only negative experiences are shared
Luddites like to recruit....


In The Pertronics failures presented only 1 has stated it was an operator/ external error. No one has stated what condition their distributer and/or coil were in at the time of install. None state the condition / age of their wiring. None state their voltage system.

Get over the hate for Pertronics, I’m not listening and you’re wasting your time. I’m sure Hotrod Lincoln has room for you in the special clubhouse. Isn’t the entry token a set of points and condenser, or is it a main jet?

PS, there are Pertronics success stories around here if you read enough old posts.

Good luck, AwDang,

I had no problems with a 6V Pertronix unit. I ran a clean/good ground wire from the block to the distributor clamp. I always carried an another distributor tested/set with points (in fear of the possible disasters posted here) - I never needed it.

However, I chickened-out, and I switched back to regular 6v points/condenser.

Let us know on your year-by-year experience.

Members here have no problem switching to 12 electronics-gizmos.
