Youll need a complete electronic ignition kit(Distributor,Electric control box aka ECU,The wiring harness and a Ballast resistor)These items can actually be purchased seperately from any parts house and "piece mealing" the parts can actually save you $$$,and you can get a warranty on certain parts,like the dizzy.
Make sure that when you do away with the current Lean Burn connections to the computer on the air cleaner,that you ensure the wires dont touch a ground. Some of those wires are still "hot" and can cause an engine fire under the right circumstances(DAMHIK)
You might want to change the carb,as the current Lean Burn Dizzy doesnt have vacuum advance,and the Lean Burn carb doesnt have provisions for a vacuum advance port,it can be drilled but its easier to change the carb. The Lean Burn carb thats on it can cause the engine to run super lean if left the way it is and will likely cause an overheating issue.
I did a Lean Burn to Electronic swap on my 78 Cordoba 400 4V. It ran great but had an overheating problem I chased for a year.I pulled the carb and put on an Eddy Carb and no more overheating at all!!
