Rain kills my LEAN BURN. Is there a Lean Burn Upgrade?

    I have an original '81 Ram Sweptline with the Slant Six/auto & 51k. Cats are gone - all else is to factory spec. When it rains, the ignition shorts out, killing the engine. A hard knock on the box with my fist will usually get it back running. I've heard there is a more reliable system that replaces the lean burn completely. Does anyone know what what might be and where to find it?

    Thanks.

    Depends on where you live. If you don't have to worry about emissions the I would find a 72-78 electronic ignition or an aftermarket conversion equivalent. Trash the cat, set base timing to 14-16 degrees, and enjoy. If you come across a 2bbl manifold and carb grab it and enjoy a good bump in power.

    Ive got the same lean-burn system that's failed and my 84 D150 is non- firing.
    Do you know where I can find schematics or where to find a conversation?

    you may almost even want to look at fuel injection. an electronic ignition conversion is about $100 and up. i think you may also need to replace the carb with a non computerized carb which is usually about $200.

    Pick up a good Chilton manual and look at the 72-78 pickup schematic. As far as a conversion kit, look on summit racing or your preferred parts supplier. I'm not sure if it's still in business, but Clifford research is another possible supplier for /6 parts.

    Forgot that some of those carbs were computerized. Thanks wolfie.

    it is not that the carbs are just computerized. the distributor for the non lean burn systems are different so that would need to be swapped out if they wanted to keep it carbed and i don't think any of the kits are geared to /6's. most are for v8's. if fuel injection with timing control was used the distributor that is in the engine should work just fine.
