  • pertronix

    ok pros its me again looking for more advice. saw an ad for a pertronix electronic breakerless ignition system from super scout specialists and was wondering if it is the same as HEI. if it is not then what is the difference between it and HEI?

    Thanks again
    joe

    Traditional HEI is G.M.'s "High Energy Ignition" used in all carbureted G.M. vehicles from '74 and up. Pertronix ignition is an aftermarket unit to convert a points distributor to electronic ignition. If you already have a Scout with electronic ignition and want to ditch the gold box, maybe an M.S.D. box will do the trick.

        Joe,

        If you plan on going EFI later on, save your $100 and do the dura-spark and holley disty conversion. You'll be time and money ahead. The pertronics is a good system, but it won't fire the EFI system.

        HTH,

        Jeff

          thanks for the info jeff. since i do plan on going efi i think i will wait and do the duraspark conversion. think i will wait to see how marks conversion does first then go from there.

          thanks again for the advice

            I'm pretty sure a Pertronix will fire an EFI system just fine.

            Lots of folks are doing it.

            What you don't get is the electronic ignition/timing adjustment if you're using a modified GM setup.

            Every rig I own now runs a Pertronix (or will as soon as the new motor is finished).

            Including the 10.25:1 5k+ RPM race 304.

            Cuts down on maintenance and worry, hasn't watered out, and I carry the old points in the glovebox on the off chance (hasn't happened yet) I fry a Pertronix.

            Try that with HEI.

            Also, the MSD won't eliminate the Goldbox.. you're still stuck using a Goldbox to trigger the MSD.

            You can use a points disty to run the MSD if you want to though.. or a Pertronix.

              pertronix

              Tom,
              Are you saying the pertronix is a magnetic pickup and will fire the GM EFI?
              Cause I think that is the system we are discussing here.

              It was my understanding that pertronix was basically a hall effect pick up similar to the gold box pick up.
              When you say lots of people are using it on efi are you referring to holley???
              I agree that holley will run off the neg side of the coil so it does not really matter what ign you run.

              Pls clearify your statements so everyone will be clear on this subject.

              And I only have to carry an ESC(gm ignition module) as a spare now. If I don't they are avail at every autoparts store in america.

                Right, I'm specifically thinking of the Holley ProJection EFI, and it'll probably fire a number of other EFIs (Including GM, AFAIK).

                The Pertronix is an all-in-one all-in-disty electronic ignition replacement for points.

                As far as everything outside of the distributor is concerned, it IS points - really GOOD points. :)

                Internally, it's a magnetic pickup and an amplifier.

                If, by "EFI" you're referring to using the full GM EFI computer controlled timing and other add-ons, then NO, the Pertronix won't cut it, only a GM HEI for GM EFI will.

                But if you don't want the computer controlled timing, you can use a points distributor with a Pertronix.

                It's important to note that the Goldbox hall-effect pickup is worthless for anything other than use with a Goldbox. You can't use the GB hall sensor for any EFI systems, to trigger an MSD directly, or anything else. It works ONLY with the factory Goldbox.


                And I only have to carry an ESC(gm ignition module) as a spare now. If I don't they are avail at every autoparts store in america.
                Just like my points.. available everywhere - and cheap.

                  Pertronix

                  Forum,
                  I am running an IHC 392 with points type disrtibutor and the Pertronix trigger conversion. I am also running a Holley Projection 4Di. Can I use the ignition control function of the Holley ECU to control the timing on my Scout? If not directly, what if if add a MSD or Jacobs spark conrol unit, could I then use the Holley ECU spark control function?
                  Thank you,
                  Mickey Miller
