I bought a running 239 in a '54 Ford.  This engine has a Carter WGD carburetor.  The carb seems to be good and the engine runs good except for being a little sluggish.  I'm thinking about going to a small 4 barrel on the 239 and using this carb on my flathead 59A.  Can anyone tell me anything about this carburetor?  What CFM?  Venturi size?  Would it be a good carb for the flathead?  What did it originally come on?  I'm full of questions and know nothing about this carburetor.  Thanks.
