Yes, the 1bbl-to-2bbl adapters exist and can be purchased from
www.Stoveboltengineco.com You can also find the Holley Carbs there too.
The Holley/Weber 5200 series is a great all around carb. Not a lot of upkeep to keep them running. Carter 2bbls or even Stromberg 97/94's will work. I suggest to stay away from the Strombergs as they are hard to find with out leaking throttle shafts and warped bases as they are 50+ year old carbs. Also the rebuild kits don't last long if you use re-formulated gas. It eats through the gaskets quicker!
