You do not want to run the Computer Carburetor. It was designed to run in a "rich mode" id the computer was unplugged. That would assure the car would run if something happened to the computer. All the computer did for this carb was to control an electronic metering rod to richen/lean the mixture in response to the oxygen sensor. If you want to run it, it will work, but you will do better with a non computer carb.
Distributor- any HEI with a vacuum advance will do. 1975-80.
