Hello;
I am planning to do a Mopar Performace style electronic ignition kit for my 66 440 C Body.
Get a good quality ECM from Richard Ehrenberg on E-bay.
Get the MP wiring harness from Mancini Racing or Ehrenberg or others online.
Buy a service part replacement reluctor and pickup plate from any number of sources. Install these in your existing (aluminum) distributor and keep your original advance timing (the MP units were timed for race use anyway).
Installation instructions are all over the web.
Install, and have a good fascmile of the original MP kits, all with readily serviced parts.
Am I missing anything?
Mark

PS, whish this site had spellcheck

The Rick E-Burg kits on eBay are good kits

When I first did my ignition conversion to ditch lean burn I got the parts I needed off a van for $5. I'm still using the Wells ECU that came off it but the distributor was replaced with an MP one ant some point and same with the wiring back when you could still get the conversion harness kit from the dealer for around $20. I originally pieced together the pig tail pieces I cut off the van the rest of the parts came from.

Now I don't even remember when the last time was I saw a vehicle in a junk yard that would have the parts to take!

The OEM Chrysler electronic ignition was phased out and was replaced with the lean burn system. The lean Burn started in 76 or 77 and was pretty much the only choice from about 79 on, until the "new computer system" replaced it.

I suspect 77 or 78 was probably the last factory original electronic ignition systems used, so its not been installed on "new" cars for 45 or so years. Funny thing, the OEM Chrysler electronic ignition system had about a 15 year run as the only factory ignition system since it replaced the points and condenser system, but most of the guys here still are in love with the points, they have not been installed on "new" cars for nearly 60 years.

I use the FBO box on my Hemi Charger. Has worked really great, only change from using a Mopar box is the need to jumper out the ballast (I hollowed out a ballast and used a wire soldered in place) and a Pertronix coil which they spec.

No issues, really like it.

Have a bone stock 440 in a 70 Challenger, running the classic Mopar electronic ignition conversion on that. Using the Jegs blue ECU (same that Rick E sells on eBay), has worked great with no issues for several years. I tried it on the Hemi and it worked well, but the FBO box seemed to give me more at all RPM’s (seat of the pants test).

Don't leave the ignition in the on position while testing with the pertronix coils. Had a few blow 💥. Also had a few more just fail. Switched to MSD blaster II's haven't had one comeback yet
