My 66 361 project is in full swing. The original, numbers matching, engine is the only engine that's going to be under the hood. The original 2bbl carb may not make it though. Weeks of soaking, ultrasonic cleaning, heating and Break-away has not been able to free it up. I don't know the exact number for the Carter carb because the tag didn't survive, but the carb body has 6-1790 embossed.Does anyone know the correct carb number for it? Thank you.
