    Hello, can anyone one here help me find a distributor for my 1976 international loadstar 1700, 446 engine or even a place where they rebuild them.
    I've been working on this truck since this spring and she still isn't giving spark. The spark plugs were changed just recently.
    I have changed 3 ignition modules, 2 coils, a rotor, distributor cap, the pick up in the distributor (its electrical) it had a little white box and I replaced it with a pertronix, but still no spark coming out of distributor, the coil sparks found that out the hard way, LOL
    thanks in advance

    Ask Bill USN-1 if he can rebuild it for you.

    If you install a PerTronix system, then all of the Holley Gold Box system must be removed.
    Should work then once the old system is removed and not interfering. .

    They are removed. The pertronix is connected directly to the coil

    Yes, why do I have no spark coming out of the distributor but there is a strong spark out of the coil (I felt it and measured it) 11.5v

    You have a PerTronix ignition system now.
    PerTronix has a website where you can access their troubleshooting info and tech data.
    I would presume some data/info was provided with the PerTronix Ignition Kit that you purchased.

    I didn't know that there was a primary and secondary. I checked the port where the wire goes to the dizzy, positive side shows a little higher in volts, negative almost nothing

    The primary wiring is the small 12V DC wires that provide 12V current to the coil + and - terminals.
    The secondary wiring is the high tension leads that go from the coil to the distributor cap and the cap to the spark plugs.
    Getting 12VDC into the coil + terminal is good.
    Getting 20,000 VDC or more from the coil secondary (ie. coil wire) is good.
    Getting 20,000 VDC or more from each spark plug wire to each spark plug is good.
    What does the Pertronix guide tell you to do?

    Photos of your distributor & Ignition systems would be useful to me in order to assist you.
    Which PerTronix system do you have? There are several to choose from depending on the distributor that is installed in the engine.
    Pertronix Part Number ______________?
    Attached are the instructions for the Ignitor II system for your engine.

    Some basic info on your engine which I assume you already know, but to be sure.....
    Firing Order of the MV-404 & MV-446 engine is 1-2-7-3-4-5-6-8.
    Attach timing light to #1.
    Distributor Rotor rotates Couterclockwise (CCW) or "Left Hand".
    Cylinder numbering is cast into each intake runner at the cylinder head.

    Where are you located?

    ok I will get photos for you tomorrow I'm am unsure what pertronix is in my distributor. I have descoverd that the pickup is working, I had the pickup wired wrong(I had connected the - of the pickup was grounded to the engine not the - of the coil). I can turn the magnet and the coil sparks, however I'm still not getting anything out of the distributor. I don't have a timing light though. Am I correct that the MV404 is timed off of #1?


    I am located in Conneaut lake, Pennsylvania

    Yes, as posted earlier, time MV-404 & MV-446 off of #1 cylinder.

    Thanks for all the help. She is tuning again, rough but running, just need to finetoon a few things.


    Does anyone know why it just wants to backfire, I can also hear that I don’t have full power, do I need to move the dizzy a little bit, or is there something else that needs to be done.
