Guys I have a 68 Chrysler 300, all original that I am going to be making some upgrades to in the near furure, one being the ignition system. I want to replace the points style with either the Mopar elec system, or the Pertronix set up, but I dont really know enough about the Pertronix to know what would be the better choice. I am not after a factory original look as much as I am the best, most reliable system. The 440 will be stock for now, but later will recieve very modest HP improvements, so a "light up your world" system is not a concern, although if the consensus says an MSD 6 series would be a good choice I'd be open to that. Can you guys tell me the good/bad points of the Mopar system compared to the Pertronix? Thanks for any help in my continuing education.  Ken.

My  is that the MP electronic system is actually quite good. The Distributors (now made by Mallory) are better that ever, and the box/system really is a good design as long as you get an orange box that isn't prone to failure. I currently run an MSD6A but I think for a mid-performance engine its really not neccessary.

Something else I thought of, when upgrading to an electronic ign, would it be nessecary or at least useful to switch to a diff alt as well? If so which one? Thanks again.

i have to agree with the MP choice. simple to install, easy to upgrade. as RR has told me in the past K.I.S.S. not sure what you are asking i regards to the alt. the MP unit does not require a higher amp alt.
What is also good about the MP setup is it's very easy to switch back to POINTS if you have a failure and need to get it down the road assuming the coil is not what failed .

You could buy a rebuilt point dist at autozone 4 cheap as you need tight bushings 4 Pertronix to function & yours is hi miles & a Pertronix II or III w their respective coil (C if Scratchn chimes in on which Pertronix). W the new MP dizzys being Mallory (I'm assuming good quality) plus the adjustability of the slot length that's a plus but once you finalize the initial you actually only need to R&R the clip on the point ones several times till you weld/file the slots 2 get total to 36-38 unless you ch cam or something to alter cyl psi which'll want a diff initial but springs will take alot of R&R ing to get the curve spot on & not sure if Mallories give you eas(ier) access to the springs than the regular 70's ones (w center clip) do. Main decision is coil/ballast combo (if going w a ECU). What double R said always carry a spare ballast/ecu and a 440 electronic dist out of a JY w a MSD blaster II coil w a MP .25 ohm ballast works good. Lots of ways 2 go w your choice & holler w what you choose & later how it starts/runs & if no trouble w it

I think the prob is the run on sentences/poor grammer/improper punctuation/abbreviations/lack of humor/short attention span (plus the caffeine)

My vote is new MP unit, FBO electronic regulator, looks just like the old one but is a circuit board. MSD ballast resister. Ran this on my 68 GTS and never had a problem using the 68 style alternator. Good luck.
Well thanks guys, a lot of info to sift through. I'll be doin some shopping soon. Thanks for the heads up.

I actually heard that the MP stuff is no longer made by Mallery but im sure if thats true. Recently , I got a NEW dist from FBO and it looks like the MP one but FBO will set the advance curve and total advance match to your set up on a dist machine. I just dropped it in the car and set the total timming. It was actually cheaper than the MP dist from summit or Mancini. I like the petronics stuff but we had 2 fail at a local shop I worked at and 1 failed on a friends 440 after 3 dyno pulls . 
quick hijack - what did that FBO unit cost you including setting the curve? OP - sorry!!

i just did the pertronix retrofit on my 440. i used the flamethrower coil and bypassed the ballast resistor. it cost me less than 100 bucks, installed in less than an hour, simple to wire, looks completely stock and runs way better than the points. i'd buy one again!

I agree with the guy above. I did the swap in no time, used the ignitor II with Flamethrower II coil. Gutted the ballast to preserve factory look. I love it. Car starts easier, runs smoother and stronger. I also carry a stock set of points, ballast, and condensor just in case the pertronix ever stops working but most guys I have seen have theirs on for like 6-10 years with no problems.
