I'm gonna get this & I'm wondering if their Pertronix 0.32 ohm coil for the Pertronix 3 is a must with this multiple spark conversion. It's an additional $40 but I have a new blaster 2 coil sitting on the shelf. Your thoughts please. Thank you for your time. EDIT Just looked up the blaster 2 specs: 0.7 ohms, 4.5K ohms 100:1 turns ratio. with the blaster having ~twice the pri resistance I'm thinking the P coil may be better but how much better.

I find it best to install Pertronix's recommended components, when you start mixing other mfg's ignition components, that when "issues" start IMHO


That being said...the blaster 2 from MSD is a .7 OHM 100:1 turn ratio coil producing 45K

The Pertronix is a .32 OHM 110:1 turn ratio, 45K output

The Petronix is the better (and recommended) coil for the III system

I think that's great advice too Robert.

You have your bases covered when you run all their stuff because they can't point the finger at anyone else.

Can we expect an update from you on this system? I'm kind of curious what to run in the future with orange boxes on the way out and my undying fondness of ballast resistors........

Yes but it'll be awhile, last Thurs a drunk driver tboned my 65 dart dd & totalled it then 2 days later a buyer showed up with cash & bought my primo 65 dart on CL so I am on foot for the moment. But I've had this pertronix system on my mind for quite awhile. I need to locate some dist bushings/buy a reamer & prep a point dist so it's tight which the P system requires & if I cant then reportedly Autozone has rebuilt point dizzys for fairly reasonable money.

I fully agree. Looking at the energy developed in the spark the Pertronix coil is way ahead of the MSD coil (more than twice the energy...).

Robert, thats what I did. I went with the autozone unit for arond $35-40 IIRC for a rebuild points dizzy. I've been very happy with the performance over the past 3 1/2 years or so.

Yeah it ought to be a killer setup. I'll post how it acts when I get to that point (which may be awhile). Roe did you go with the P igniter 3

I've done this research recently for a friend of mine, and to get all the "good" benefits of the Pertronix III ignition, you should use the Pertronix III coil. That includes bypassing the ballast resistor.

I'm interested to know as well, since I think we are going to stick with the Pertronix II in the rebuilt/re-curved distributor from RockAuto. My very sketchy recollection of my DSP classes in college just seems to tell me that there is no way a rounded lobe can trigger better or more reliably than a magnetic "star" point. That was one of the misgivings I had about the PIII, however, I know technology has improved in 20 years and it's been used in other applications with some success.

I think **MANY** people are anxious to hear first hand experience.

The ballast should be eliminated in all Pertronix applications/conversions, the Pertronix III needs 12 Volts nothing less

I went with the ignitor II setup. I kept the ballast in place, I just gutted it and soldered in a thick wire. 8 or 10 guage or something like that.
