I have a 1986 Dodge 250 Ram van. I’m going to be replacing intake manifold and carb on my 318. Also going to add headers and dual exhaust. Mostly to free up the engine for better fuel economy. This engine does have the lean burn system on it now from the factory. Can anyone give me some pointers on how to remove the lean burn and any smog junk I don’t need? Im going to also use MSD ignition. thank you!
