I promised pics but still havent gotten the shoddy workmanship cleaned up, but will post the "how to" segment. If ya hit a bump just ask and I will try and answer.
If you are wondering why I would do this lets just say, the car was a friend of mine that passed away at an age we wont discuss, but he knew me as a car guy and always brought his broke junk to me to fix. Anyways when his wife told me he wanted me to have the car to come get it I did, and I did know it had started having drivability issues but I was not ready for what they were.
Hard to start, wouldnt idle, wouldnt hardly get out of its own way, and this is a c-body 440ci powered car, with roughly 80k actual miles. Gas milage? glad you ask, 2-3 MPG IF you were lucky. Needless to say first thought was carb, cleaned it to with-in an inch of its life, to no avail. Tried timing, nope, new plugs, wires, cap, rotor nope, still no help. Talking to a buddy of mine that is a Mopar Junkie gave me an electronic/vacuum advance style dist and said junk the lean burn and put this and an old school carb on it, and your prob will be solved.
Which lead me to another problem, the elec boxes for mopars arent 'zactly cheap, and no wiring for them to boot. So there had to be a 'cheaper' alternative.
When I first did this "Lean Burn Delete" it cost me a whole 35 bux for new parts, I had scored an old NON-Lean Burn Thermo-Quad in the need of a kit, and a friend gave me the RB Electronic Distributor, and its needed due to Lean Burn cars have no Vacuum advance. I dove in one fine day during the winter, ( think it was 36-37 degrees with a 20-30mph wind ) I do live in the Texas Panhandle.
Ok now ya have needed BIG parts, (dist, and carb) install those, hopfully on a warmer day than i did it on. I had bought the DR-100 Duralast Gm Module, and I will list others if you arent big on AutoZone. (NAPA Echlin TP-45, AC Delco D-2906, or Standard- Bluestreak LX-301.) I just mounted the module directly to the inner fender well on the passenger side with machine screws ( I think I used #8-32 with matching flat washers and lock washers and nuts) using the whole tube of dielectric grease that came in the box @ that time. (think they sell it seperate now) You will need to source either the connectors from a junk GM dist or use female spade connectors, you will need 5 normal sized (1/4") and one small sized (3/16"). On the 12v side of the ballast resistor hook one wire to it and the other end to the B+ side of module. Run a wire from the C terminal of module to the + side of coil. The last connectors goes to the distributor. If the car fails to start, or runs very poorly swap the 2 distributor wires at the module. and thats it...I also bought a different coil, and I suppose any electronic ignition coil would work, but I bought the cheapest E-coil I could find, which in turn ends up being one for a Ford, Part no C-859/ FV-55. It was 14.99 when I did all this the price is up to 23.99 now according to the A.Zone site.
I unplugged the mess of wires/vacuum lines going to the Lean Burn, stuffed em behind the fenderwell where they still reside. Took the lean burn unit it self off of air cleaner and dropped it into the dumpster, made a lightweight plate to cover the holes on the air cleaner and used the screw holes that were already there to mount it.
Oh and you maybe wondering about the fuel mileage now... 14 ish in town, will burn the right rear tire off of it if you want it to, and has that magical Thermo-Quad Growl when stood on.... It runs the way it should....
