The Edlebrock 1400 series carbs are exactly the same, for example... you can order a rebuild kit for a 1406 carb for your Carter. The metering rods and jets all interchange, you can even use the tuning chart on Edelbrocks website. Need more or less pump shot, order the pump shot kit for any Edlelbrock 1400 series carb. Running too rich at cruise, get the spring kit for the Edelbrock carbs to adjust. These are super easy to work on and tune. If you have a wideband O2 sensor gauge such as Innovates kit, you can see in real time what your adjustments are doing and exactly what your air/fuel ration is at cruise as well as wide open throttle. You don't need a wideband O2 gauge to tune a carb, but it totally simplifies the process. These along with the Edelbrocks are good carbs. Your money and your time though. I've been there and done that with Carbs, now I'm into fuel injection. Good luck with whatever you decide to do!
