coil question

or buy a MSD box and pick any coil you want.

I'm no ignition expert, but I've heard it's the ignition box that makes you need a ballast resistor and the coil doesn't matter. e.g. any Mopar ignition box = need ballast
MSD box = no ballast



I know the ballast blow, but just keep a couple extra in the glove box.... or buy a MSD box and pick any coil you want.

On summits web site you can select coils by primary resistance. For example the Mallory 30451 "E" core coil has a primary resistance of 1.4 Ohms. I think that is close to combination of a stock coil primary resistance (around 0.7 Ohm) plus the ballast resistor (around 0.85 Ohm.)

Wondering if there is a coil out there i can use in place of the stock coil that i dont need to use a ballast resistor with?

explain about the petronix kit, does it eliminate the ballast and ecu box or?? Is it as good as the stock electronic ignition? Does it have as hot a spark as electronic? Reliable?

sounds good! so what do i need to do, buy an old points distributor and put the petronix kit in it, drop the distributor in the engine and remove the ballast and ecu from the car? will the distributor plug up to the car the same as the electronic one did? seems like i will have to rewire the car..?

with the stock elect dist set up,just swaping the dist out with a points style,the black points wire goes to the -side of coil removing the stock elect -wire from coil.leave elect dist plug undone/taped up. I have to readjust points every 3-6 months to keep it starting with a flick of the key.change them 1x a yr.

going to a pertronix conversion,i just pick up a reman points dist from autozone for 30 bux or so. then the pertronix Ignitor I with a flamethrower 40,000 volt chrome coil-1.5 ohm. install in the dist/set airgap with supplied plastic feeler gauge and drop it in.

red wire to +side of coil with the stock keyed power wire.

black wire to -side of coil plus the green tach wire if you have it.

put a jumper in place of the BR or gut the shell and hide the by-pass so it looks like you still have it.

set timing and forget it. I replace cap.plugs.wires about 3-4 yrs

it has got a hot spark and revs to 15,000 rpm.

I just got a pertronix Ignitor I (kit-MA187) conversion and flamethrower chrome coil for the Mallory duel point dist i got from RapidRobert a while back.(RR- I fried a set of those points trying to set the gap)

on my 88 440 truck I have the ecu uplugged and removed,BR by-passed and just taped up the empty ecu plug and hide behind fender brace.

they are simple to hook up and work flawless. I have never had a reason to try the Ignitor II or III kits or the ready to run dist they sell. I have used 15-20 ignitor I and chrome coils fixing a lot of 5th aves/mopars with elect or points dist for other people when they have ign troubles.

it may cost a few bux to swap it over but the old "let me down" ecu stock elect crap is a thing of the past.

First question comes to my mind,,, ARE YOU HAVING AN ISSUE WITH WHAT YOU ARE RUNNING NOW?
If the answer is no,, then why change ?
if the question is yes ,,
What are your issues?
I for one do not run any ballast on my coils,, not on the street or the strip!
I have not lost a coil yet!?? my street car have ran it as long as 10 years, when sold it , it is still running to this day with a stock coil and no ballast.

nor an ign box!?

Makes it hell to start if sets a few days,

you are aware that you will still need a ballast with points, right?

this is correct. you will also need to use a stock POINTS style coil

but.. to get the dist over the counter you tell the parts monkey you need any yr mopar that would have come stock with points. say..67-71 dodge/plymouth/chrysler A,B,C body.

then you can just drop it in the 440 and hook the black wire to -side of coil,tape up the plug for elect dist,leave keyed hot wire on +side of coil(after swaping for a points style coil),AND the BR in place. I have run lots like this with no trouble,just a tuneup/adjustment every yr.

now going to pertronix points conversion,you have the points dist to install the kit in. FYI- it will have a slightly better spark curve as a bonus over the elect dist.IMO.

now you by-pass the BR with a jumper,install the 40,000 volt pertronix coil, hook red wire along with keyed hot wire to +side of coil. the black wire to -side of coil(with green tach wire if you have it)

follow the directions and use the .030 plastic feeler guage supplied to set the airgap on the Ignitor unit.

it will float the valves before it runs out of spark.

so no ballast needed with petronix kit right? i wont be running points, only the petronix kit in a points distributor.

i need to just figure out where the voltage drop is and rewire it.
