http://cgi.ebay.com/ebaymotors/NOS-...690QQssPageNameZWDVWQQrdZ1QQcmdZViewItem I'm using Carter-Webber progressive two barrel carbs on my offenhauser dual intake manifold. I got them from Tom Langdon's Stovebolt Motor Company for a decent price. If you search the threads here on Carbs you'll find the car they originally came out of and might be able to find them cheaper. Langdon also sold me the linkage, which works nicely.
If you are considering dual exhaust, which is reccomendable if you are going with a 3/4 cam and dual carbs, think about Fenton cast manifolds versus tube hedders. Tube hedders rust internally a lot quicker where the cast dual manifolds will outlive you and I. If you go with Fentons Patrick Dykes of Patrick's Antique Auto is in the process of producing the Fenton Dual Intake Manifolds, which nobody has made for a long time. They bolt right up with the Fentons as opposed to when you use Offenhauser you've got to grind both the mount tabs and the tubes on the Fentons to get them both to bolt up to the engine.
