The rebuilt Holley 1920 1bbl that came with my Dart was terrible. I'd plan on going through a rebuild and verifying float level, etc. Havent installed it yet, but I bought rebuilt old stock carb for my super six setup on Ebay. Thought that maybe it being old stock the throttle shafts and all might be in better shape than one that's been rebuilt too many times. Think I paid about $75 for it and no core charge.
