You have to get the configuration code from the techs at Barry Grant. The code merely defines the particular configuration of the carb they define for your specific application i.e. CFM, venturi size, jets, vac or mech secondaries, Speed vs Mighty vs Road etc. Your cam, heads, intake, tranny, rear end gearing, weight of the car etc. will be factored into the equation. It only takes a couple of minutes if you have the info in front of you. The tech will give you the config code and since they don't sell retail, you can take the code to any shop that carries BG carbs and they will order it for you. Southern Automotive bought mine as part of my engine build.
