I also have the lean burn system on my '78 360, I was told to change the distributor and that would eliminate the LBS.Bill

Mopar makes a wiring harness for a E.c.U for a factory style elect. ign. You also need to change the carb, the intake would be a good idea also. You can still maintaine 2 bbl. set up if you like. I did this same conversion on a 79' volar'e, but i went with a 4 bbl. it was super easy and cheap. I think the harness was under $20.00 from mopar performance. good luck.... Gram

After I convert the lean burn system what do I do with the computer and all the wires do I still need some of them, or can I get rid of them and take it off completely?

The kit from mopar comes with a wiring harness and instructions, you don't need to change the the carb to get away from the lean burn system.

Dear Kris,


not a problem. remove your ELB wiring all together out of your loom. It should start around your air cleaner. When removed, find your balast resistor, take it away, and the wires at each end of it - join those together so you get a full 12volts. Purchase yourself a new electronic ignition distributor with a vacuum advance, and a new coil to suit - a 2 barrel or 4 barrel carb of your choice (I use Edelbrock Performer on my 360 - and it all works like a treat). Thats how it works here in Australia, I hope it helps you Kris.


cheers - fletch - Australia

If you by pass the ballast  resistor and run a full 12 VDC all the time you will go through coils at a very high rate. Your electrical system by passes the resistor when cranking but goes to 6 VDC when running to keep your ign. system alive longer. If you go with the Mopar kit and follow the instructions that come with the kit you will have a system that is dependable and will last along time, you won't be sorry you did, go another way and you could be setting on the side of the road wishing you had used the Mopar kit !!!

I have a 79 Dodge Magnum that formerly had the Lean Burn..All I did was unplug the computer and, after verifying with a test light that I still had voltage to the ''pos'' side of the coil with the computer unplugged, I trashed the lean burn distributor and picked up a '72 points-style unit from Autozone....I taped up all the sensor connectors into the engine harness and did not fiddle with the ballast resistor...Car now runs like a scalded dog, even with the Holley 2280 2bl still bolted on the intake...A Petronix Ignitor kit with Flamethrower coil is waiting in the wings when the point set do go bad...

I have a 78 Monaco with a 318 lean burn. I want to 86 this set up, and go with a electronic ignition. I noticed in the july 04 issue they tackle this infamous system.  I wonder, if one could  modify the SCC distributor.  The electronic distributor is exactly the same as the SCC except that the distributor weights are gone.


Any feedback appricated
