Stock coil or should it be changed? Points to Electroni

Stock coil or should it be changed? Points to Electroni - 04/11/09 08:41 PM

I plan to install a Mopar Performance electronic ignition setup on my 1970 Satellite, 383 engine that still has the stock point type distributor in it. My question is, will I need to buy a new coil or can I use the old existing one? I thought I read it needed to be changed for one compatible with electronic ignition? If so, Can I just get one from a 73 Chrysler or something that originally had electronic ignition or will I need a performance one? What do you guys recommend? This is not a race car, just a sunday cruiser...stock 383 with a 2-bbl. Thanks!

your same coil will work you are now just switching it's primary off/on electronically instead of mechanically. I'd get the 1.25 ohm ballast & I would highly suggest that you get the MP chrome box instead of the orange ecu even if it means you buy the dist/harness/ecu seperately instead of the orange box complete pkg. EDIT if you do change coils yes a 73 up stock one will be fine as you would have exactly the same as a factory oe 73 up setup but unless you had one in your stash you might get a hotter one such as a msd blaster 2(which MAY change the ballast requirements) but your stock coil will work fine.

The Mopar kit comes with a new ballast, do you think its the 1.25 ohm? I'm not sure which ohm ballast is currently on my car, I would assume a stock one. Just trying to set myself up with all the right parts while waiting for my kit to show up.

(1) yes (2) You have the orange box(kit) ordered?

Yes, it comes with the orange box. I am buying a set from a member here, its new in the box, never used.

The odds are very high that you wont have a single issue with the orange box.

While updating the ignition, consider the following:

1. Upgrade to the chrome box
2. Upgrade to the Mopar Blaster coil
3. Upgrade ballast resistor to 0.25 Ohms

Next when setting the timing, note that the Mopar distributor has 20 degrees and you should set the inital advance @ 14-16 degrees. Making a total of 34-36 degrees.

Just my $0.025..

Did you mean 1.25 ohms? The one that comes with the kit from Mopar Performance?

The electronic kit comes with a 1.25 Ohms but when you use a Mopar Blaster coil (Mopar #4876732), you use a 0.25 Ohms (Mopar #2444641). Because the Blaster has higher output voltage and can handle a higher input voltage, when using a 0.25 Ohm vs the 1.25 Ohms the coil sees a higher voltage.

Thanks for the help, just to clarify, if using the stock point type coil currently on my car, just use the 1.25 OHM resistor that comes with the kit, if I use the Mopar Blaster coil, use the .25 ohm resistor. The purpose of the Mopar blaster coil and .25 ohm resistor is for a hotter spark? Better performance? As mentioned, this car is all stock, 2-brl carb, 383, automatic. Not a race car by any means.

(1)yes (2) yes (3)yes,hotter spark/better performance

In a bone stock 2bbl 383 car I doubt you'll feel any difference between the blaster and the stock coil. I put one on a smogger 440 once, which you would think would need all the spark help it could get, and it made no difference on my seat-o-pants meter.

was that with using the the .25 ballast

I'd avoid the "el crapo" Chrysler Electronic Ignition,....IMHO your much better off with a Pertronix Ignitor II set-up and coil,....eliminate the ballast in the set-up,





in the Pertronix conversion you get to keep your original point distributor, just install the coversion kit, everything fits under the stock cap......

!!!REALLY!!! I guess the hundreds of thousands of Chryslers that ran for hundreds of thousands of miles using the el crapo Chrysler ignition were just, lucky?

I put on of these in my '70 soon after they came out in, when, 72? I owned that car up into the '80's. Later, I ran a 340 in my old FJ40 Landcruiser, and guess what? I ran an el crapo Chrysler ECU in that too!! Last time it ran, it ran with the el crapo ECU

Yeah but why add in all the extra wiring and clutter when the pertronix will keep it clean, simple and stock looking and do just as good of a job at it?

I would not use a .25 ohm ballast resistor, if your going to use a Mopar/MSD blaster coil use the msd .85 ohm ballast its a super heavy duty one, if you get the coil it might come with one, the MSD blaster i got 15 years ago had on in the package and its still on the car. And also use some washers behind it to raise it off the firewall so it will have some air movement behind it.

Did you mean to replace the MP resistor(1.0 ohm) with the MSD .85 resistor??
Thanks

Re: Stock coil or should it be changed? Points to Electroni - 04/12/09 04:14 PM

I would not use the .25 ohm resistor it will give more spark but i don't think one that low is recomended for a street car, it may overheat the coil. the 1.0 ohm mopar would be fine, i like the MSD .8 ohm, its just a heavy duty looking resistor i dont think you would see any seat of the pants dif between the mopar 1.0 & the MSD.

you don't need to worry about ballast resistors or coils. i would just install the electronic conversion kit as is. it already comes with everything you will need. i don't think you need a hotter spark than stock as you said it is a sunday cruiser with a stock 2bbl 383. electronic ign. is a smart upgrade.

My pickup has a 360 that I converted from points to Pertronix. I just put the points back in it, and I'm going to UPGRADE to el crapo Chrysler electronic ignition. The Pertronix crap has left me sitting for the last time. I know several other local guys that won't use the Pertronix set up again. Never ever had a problem with the Mopar ignition set up.

Re: Stock coil or should it be changed? Points to Electroni - 04/13/09 02:48 AM

.......if there's any problems with a Pertronix installation, it's usually due to an installation error, retaining the ballast resistor in the set up,....as the Hallcell requires 12 volts, using the wrong coil, the Pertronix requires a coil in the 100:1 TR and 80 milliamp range, or gapping the airspace with a steel gauge, or installing it on a worn distributor shaft, running soild core wires, or installing some foolish MSD set-up with it.......I've run Pertronix conversions on all my cars for YEARS, with not one single failure......where as the "El Crapo" Chrysler set-ups were always frought with problems,........I'm not new to Mopars, I've owned and driven them for over 30 years.....IMHO, the Pertronix set-ups are a blessing over the factory stuff!............perhaps you should throw a nice "lean burn" ignition set-up on that pick-up, now there's a real peice of crap, from the factory! .....

Don't really want to debate the point of Pertronix vs. MSD vs. Mopar...

But ...
IMHO
A good starting point is the Mopar information, then after reviewing this go whatever way you may want to...

with daytona

with dayclona

I have been running a pertronix conversion with the pertronix flame thrower coil in the points dist in my 85 truck,68 dart,67 polara for over 9 yrs..same one just swap the dist/coil around
never had a problem..expt when I used a diff rotor button..it gave probs till I replaced it with a pertronix one

I have swaped it right into a couple diff dist over the yrs and just use the .030 plastic gauge they come with to gap it


all the elchepo stock ecu crap is still hooked up in the wire harness and it has 2 wires from dist to the coil and the one keyed wire from the harness...just unhook the elect dist plug

the points vac dist will give a little better curve on the timeing when using the "stock" dist in a stock points car over a stock smog dist

when it was in my 68 dart I used a #10 stranded wire solderd in the shell of the ballest resiter, to by pass it to give the pertroinix a full 12 volts to work with the 40,000 volt flame thrower coil

just like the ad said..throw the points/condencer in the glove box ...but you will never need it

thats my 0.05$
