Rid of Mopar electronic mess! - 05/17/13 01:08 AM

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.

On the ballast resistor, just gut it and straight wire it on the inside. Will look stock.

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

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!

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.

Re: Rid of Mopar electronic mess! - 05/17/13 02:19 AM

Thanks for the info. guy's. I searched more for a vacuum advance and it seems like what I have found is when it hooks up into the dist. on the plate it goes in from the top of the plate where the ones I have or have always had comes up from underneath the plate! Which one is correct? And I learned to dial in my onw distributors a few years ago.I just always had to pull it out take it apart which takes 5 mins. and another 5-10 mins. to put it back together and back in with a different set of springs. I learned it all from all the guy's on Moparts on how to do the dist. tuning!

Check this out, 69 stock dual point and it will have hidden HEI module and shorted ballast resistor.

Is your car auto or stick , stick is 10.5 ...

Also there is more to setting up the distributor than changing the springs.

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.

Re: Rid of Mopar electronic mess! - 05/17/13 06:27 AM

Yes I know, I had welded the slots a couple years back to give me 38 total degrees advance all in by 2000 rpm with 15 initial in a 9.0 compression 383 with the compcams. XE268 cam. And the slots were filed to give me 23 degrees adv. I just played around with the springs to get the advance to come in at 1200 and all in by 2000. I used the mallory spring kit. That gives me my best performance. And it is a four speed trans. Thanks!

Re: Rid of Mopar electronic mess! UPDATE! - 06/09/13 04:52 AM

Okay, For the past month I have been experimenting with the 90's mopar electronic ignition and a petronix and coil in my stock distributor and a newer mallory built mopar distributor and I have to be frank, the petronix revs up so much quicker than the other two elect. setups! I do have the ballast bypassed on the petronix and I have the orange box with a .8 resistor for the other elct. setups. But with the petronix ignition the timing marks seems to jump around 2-3 degrees with my dial back timing light and it did annoy me. Can anyone explain to me why this is? Thanks, Dave!

Which Pertronix did you install? The II is supposed to be adaptive, maybe its doing its thing.
Posted By: superbeedave

Re: Rid of Mopar electronic mess! UPDATE! - 06/09/13 06:24 AM

#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.

Re: Rid of Mopar electronic mess! UPDATE! - 06/09/13 02:27 PM

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.

Twist the rotor back & forth lightly just not enough to get into the springs & see how much rotational play you have which is a measure of how much slop there is between the dist lower shaft tang & the intergear slot it fits into & check the dist shaft shaft/bushing wear as Supercuda said as play in either of those will make the marks jump around (spark scatter) just like a worn timing chain will & you see it with the light.

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

Re: Rid of Mopar electronic mess! UPDATE! - 06/09/13 03:49 PM

Yes I put the petronix in a points dist. and it has new bushing in it and all three of my dists. have been setup for 38 total mech. advance
and springs are in all dists. to give me advance starting at appro. 1250 and all in by 2000. And it does have the pert. rotor. Like I said the marks didn't jump around with the mallory chrome hipo. coil. I have gone thru dists. 100's of times and I don't see anything wrong with any of the dists. Maybe I am missing something! I usually play around until something jumps out at me to tell me that is the problem!
Thanks for all the replies guy's!

Re: Rid of Mopar electronic mess! UPDATE! - 06/09/13 06:37 PM

you have the ignitorII correct?

does it have a fixed airgap?

I have bumped mine when R&R the dist and had issues till i reset the gap at .030

my pertronix in my mallory duel point dist has a fixed airgap.

just thinking out loud.

There is your first problem , the orange box , it's as big a POS as a cone type suregrip ...

your timing is bouncing around probably due to slop in the distributor to oil pump drive clearances ...

Then the problem here is the coil , pertronics coils now are off shore junk. Paint the mallory coil black and run it .

JohnRR, That's the same thing I was thinking, The coil is causing the marks to jump around 2-3 degrees and I also think the orange box is a piece of crap. The chrome box and is in the near future and I also have a .25 resistor waiting for that chrome box in my tool box.

Re: Rid of Mopar electronic mess! UPDATE! - 06/10/13 01:48 AM

Funny as many say the orange box is no good but mine has worked flawless since 2000 when I first put it on my boys Dart. I now run it on my 63 with an Acell coil. When we took it off his car and put MSD on it it did not sound any different and started the same. It also did not go any faster with the MSD. Sorry to hear so many have had trouble with them. Mine never misses a beat and the timing is right on all the time. Good enough for 6500 RPM and 10 second et's. Ron

Despite having a number of Mopar elec ignition parts all new I have had it with will it with the no start syndrome. Every spring I would have to play, with the ignition change this reground that, now no problem for 6 years using a pertronix and or point dist. The best place to mount a MSD igition is the garbage can I have two setups that went bad internally fixed and returned to me to fail again When your car goes .4 faster by using a stock setup over the MSD then they can keep it! MSD do not belong on a street carmy 10 cents

Re: Rid of Mopar electronic mess! UPDATE! - 06/10/13 02:10 AM

One has to wonder how the heck millions of Mopars survived with the electronic ignition some of you have issues with.

I've run the Orange ECU in numerous cars over the years with no problems. Closest I ever came was when an Accel yellow coil failed when it got hot.

Put a timimg light on it and tell us what the timing is at 3500 , 4000 , 4500 , 5000 , 5500 ...

I'll say this much , back around 1984 I put an Accel dual point race distributor on my dads duster with a 340 , switched it to mopar electronic after my brother kept leaving the ignition on and burning out points while he was PARKING in the car. The car ran so much better and sounded stronger with the Dual point than it did wit hthe orange box.

Comparing an orange box from 13 plus years ago to something current is not an apples to apples comparison if the old ones do not pull timing out like the current ones do.

I have looked at my timing up to 5000 rpm and it holds good as it does not take timing out. Like I said my boys car ran just as good with the orange box on his car as it did with MSD ign. Yes it is 13 years old but it is still an orange box. Maybe they were better back then as it seems most who have problems have bought their orange boxes within the last five years. I have also never had a ballast go bad on me but yet I always hear about everyone having to replace a ballast resister. Maybe I am just a lucky one John ? Ron

instead of just opening the coil primary circuit when triggered by the dist coil pickup it improperly electronically delays that precise moment at higher RPM's which retards the timing (kinda like a dialback timing light does). An ECU is only supposed to open/close that circuit when triggered by the dist but evidently something is electronically wonky in some of the newer orange boxes causing it to do something (delaying the opening of that wire) that it should not be doing

Robert I don't think something is wonky in the electronics , I think it's by design. Before the current Mallory internals of the supplied with the electronic conversions the distributors supplied had 30 degrees or more of mechanical advance. The easiest way to make a one size fits all conversion was to have the electronics pull out timing instead of instructing the end user to do the trial and error process of welding the slots to limit mechanical advance.

Double R that does make sense cuz you certainly wouldn't expect it to be doing that (or be electronically capable of doing that) if it wasn't designed into it

Re: Rid of Mopar electronic mess! UPDATE! - 06/10/13 02:37 PM

Is there any way short of checking the timing at 5500
to identify bad orange boxes?

We purchased ours quite a while ago and haven't installed yet,
I would like to avoid replacing after the fact is discovered.

I still have the conversion pack box, but can't see any date on it.

The part# is 23690428, is that any clue?

It's not necessarily BAD , it's working as designed

The easiest way to know if it's good or bad is to just ASSuME it pulls timing and use something else.

Re: Rid of Mopar electronic mess! UPDATE! - 06/10/13 05:23 PM

Something that I remembered after reading more on this is how Bill Jenkins used to retard his timing in high gear years back when he ran a points dist. He would cut out one set of points so in high gear and high rpm he retarded his timing. Seems he used alot of advance down low but took some out up top to mph better. I have heard of others doing that also.
It does seem that everyone having problems with the orange box have bought them in the last few years and I have heard others say it took timing out as John said. The best thing to do is try another ign and see how it runs. All I can tell you is my 13 year old orange box ran as fast and started as good as the MSD did on my sons car. Ron

Re: Rid of Mopar electronic mess! UPDATE! - 06/10/13 06:13 PM

Pertronix, there are two "r"s.

Doesn't almost every Mopar vacuum advance unit have an adjustable stop that one accesses with an Allen wrench through the vac port? The one that Accel sells or used to, modified for GM distributors?
So why can't one buy the 9.5 degree one and limit it to 8.5 degrees?

I haven't had to do this, am quite happy with my Direct Connection HP electronic distributorand MSD 6.

Ron, A prestolite dual point has one wire going to/from it that triggers the coil.

How would Jenkins take out a point set on the top end?

Would you add a second wire to one point set to open or ground it with a toggle switch?

Sounds like a good experiment for me to try as I run a prestolite dual point and am always looking for free MPH!!

Ideas for execution anyone?

You'd have to solder an appropriate thickness of feeler gauge on the back of the can on both sides of the arm to limit the notches' travel into the can to change (reduce) the total amount & likely could file the notches to add total. Using the 3/32" allen wrench doesn't change the total but changes at what vacuum level the curve starts (& therefore ends) & it's linear

I actually still have the Car Craft mag from around 1971 with the article but I would have to dig it up. Normaly dual points overlap each other for more dwell but I believe he ran on the first set of points until 4th gear and then brought in the second set of points which would fire the coil later and retard the timing. I wish I could dig up the mag but I have tons of mags from about 1969 to now. Ron

That sounds more like a 'dual stage' timing-setup in one distributor by using both points sets seperatly.

Hey guy's, I know it's been a few days since I posted anything. It's interesting just reading all of your guy's posts. I have decide to go back to what I was using for years and that would be the 90's Mopar electronic ignition. The mallory built distributor design sucks in my book! My welded up slots in the early version to give me 23 mech plus the 15-16 initial works well. There is just something weird with the mallory dist. maybe the reluctor is really off a degree or two. I know when I compared the two reluctors the mallory one seemed to be off with the mopar reluctor just a hair. Also the mallory dist. have you noticed that the bottom of the shaft where it goes into the oil pump shaft slot is clocked off a tooth as compared to all the other dists. for big block mopars. What will happen is when you install this you will have to rotate the dist. pretty far to get it to run which throws the vacuum adv. way around towards the heater hoses. So what I did to keep the vacuum advance in the middle where it should be is using a pair of long needle nose pliers rotated the oil pump gear one tooth clockwise to keep lined up. But then again mine could be the only one like this but Summit racing sent me two and they both were alike. Thanks, Dave

Also the mallory dist. have you noticed that the bottom of the shaft where it goes into the oil pump shaft slot is clocked off a tooth as compared to all the other dists. for big block mopars. What will happen is when you install this you will have to rotate the dist. pretty far to get it to run which throws the vacuum adv. way around towards the heater hoses. So what I did to keep the vacuum advance in the middle where it should be is using a pair of long needle nose pliers rotated the oil pump gear one tooth clockwise to keep lined up. But then again mine could be the only one like this but Summit racing sent me two and they both were alike. Thanks, Dave




You can move the wires over a tower to get the clocking correct ... oh wait , then it wouldn't be correct to the field service manual ...

The older mopar distributors are notorious for the rotor phasing to be off which is why Eberg sells the rotor with the extra slots to correct phasing.

Ran the dual point setup on my Duster used switches on a Accell dual point turn off one set for high end charge. It works but pertronix is easier as is stock points but use a heavy set
