After years of running the Mopar electronic ignition in my 69 Superbee I finally decided that I wanted to do away with that aftermarket look and go back to stock. Well, sort of! I put a Pertronics unit with their black coil in my stock recently restored distributor and it seems to start and run better than the electronic ignition. Still trying to figure out how to keep stock looking but bypass the Ballast resistor. I put a jumper wire on and drove it around for a few days and I liked it. Of course had to also tweek in my advance and the spring setup. My biggest problem now is I need an 8.0 or 8.5 vacuum advance. It seemed to run cooler at highway speeds with 56 degrees full advancement with the other setup than the 52 I have now with my stock dist. Does anyone have an idea on where I can get one at? The only ones they seem to offer or have is either a 6.5 or 9.5. The electronic dist. plate is different than the 69 stock dist. plate so they will not interchange. Thanks! Dave.

Get the 9.5 vac adv can & JB weld strips of feeler gauge on the back side to limit the notched arms' travel into it. EDIT If you need an 8.5 can?? install the 9.5 unit & at idle pump it up with a Mityvac till it gives you 17 (8.5 X 2) additional advance above your initial timing & note the vac reading on the pump at that point then remove the can & pump it back up to that number & select the appropriate thickness of feeler gauge(s) to limit further travel of the arm into the can. You'll likely have to retard your initial so you can squeeze in that much additional just for this occaision

On the ballast resistor, just gut it and straight wire it on the inside. Will look stock.
I gutted mine and saved the spades off the ends,then solderd them to a #10 stranded automotive wire,stuck the wire and spades back thru the shell, looks stock and un-molested.
the black coil is a pertronix coil correct?
I used a some of stock plastic wire loom stuf on the red/black wires comeing from the dist to help hide it looking like only the black wire from a points dist.

Right on! I'm restoring my factory distributor too and will actually be keeping the breaker points. That's right, no more 1970s Mopar ECU under the hood. Not even electronic ignition of any kind. Just simply 1969 stock. Get a hold of moparts member Paul Petcou known here on the forum as Beeware. Paul races in Pure Stock Muscle Car Drags and has a Sun distributor machine. Send him your distributor and he'll dial it in for you. He'll also give you the skinny on how the Pertronics set-up actually performs in the quarter mile which may surprise you.

Is 9.5 stock for my 69 383 or is 6.5 stock? And where or who would have it? I have been having trouble finding a vacuum adv. for my it. And gutting out the resistor is kind of what I had in mind. Thanks!
Is your car auto or stick , stick is 10.5 ...
Also there is more to setting up the distributor than changing the springs.

Is that a distributor for a 340 or 383?
That is a small block dual point, but the same could be done to a big block , the breaker plate is interchangeable. I had a single point Chrysler housing that had a prestolite dual point breaker plate installed in it.

My 64 300 had a dual point distributor in it when I bought it. The timing jumped around a lot, to the tune of 10 degrees or so. Turned out the distributor was worn out and sloppy.
I would go back into the distributor and see if something was loose.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

#1, I had it for a little over 3 years and just recent I decided to try it out. What was weird was when i installed it a few weeks ago I used a Mallory high perf. coil for points and the timing marks didn't jump around. Then when I put on the petronix coil that is when the marks started bouncing around.
did you put the pertronix in a points dist?
I get a reman from autozone for 30$ and drop in the pertronix with flamethrower coil and never had it bounce or give any trouble.
the points dist has a slightly better advance cure to it than the elect dists.
also you need to make sure you have a pertronix rotor button,I replaced mine one time and it give me fits as it did not fit the pertonis piece very well and would let the rotor not line up correctly at a cap term.. missing every now and then. replaced it with the pertronix rotor and have been running it 15 yrs now.
IMHO,the ignitorI is all you need,revs to 15,000 rpm and runs dang near under water in the 4x4
