I had two pertronix, one in my mustang, and one in the truck the mustang lasted about 10 minutes, the truck about 6 months. Only after I "UPGRADED" my ignition, is the only time in 31 years the truck has left me stranded. I have come home with gas just pouring out of the carburetor, with 2 pushrods, come completely out of there designated locations, missing, popping and making all kinds of racket, but I made it into the garage. And all this after about 8 years, I finally got my wife to come with me, along with my 5 year old daughter. We got to discover the bus system in our city, and go back home to get the little Ziploc bag, that I took out of the glovebox the day before for something else and drive back and sit in pouring rain, and wind switching everything back over. No I would not recommend pertronix. I asked this very forum if anyone had similar issues, and of 10 replies, 4 were of the "I will never use pertronix again" variety, these along with my 2 bad experiences makes 6 out of 12 against, not a real good average as far as I can tell. I got a lifetime supply of NOS Points, and can sit there and fester with them for the rest of my life, and still not come close to the misery of that one day. I can't even recall points ever even being any sort of "trouble" in any vehicle, However the HEI would probably do fine.
