Lean burn to old style ign swap?

The diagram Del posted above,tells you everything "you're getting yourself into". Which ain't much. LOOK at the diagram. It's all there. LOOK at the diagram. It's very simple.

As to the why. You can almost get an HEI module at WalMart. Everybody has them and they're cheap.

Why the gm module? Also, not sure what i'm getting myself into as far as using plugs that mine doesn't have (ex the connector for the mopar module if i was to go that route), and what sensors that the current brainbox uses that would be used/discarded. Never messed with this stuff so any basic tips and such are greatly appreciated
