Here's a link to an Ebay auction for the same carbiretor:

http://cgi.ebay.com/ebaymotors/HOLLEY-ECONOMASTER-CARBURETOR-CHEVROLET-V-8-2Bbl-NEW-/320563951667

No CFM rating, but it's a Holley replacement for the Rochester small-bore 2-BBL carb that was original equipment on the 283, 307, and 327. It probably isn't as good a carb as the OE Rochester, because it won't be calibrated for a specific engine/trans/gear ratio setup like an OEM carb would be. Typical Holley approach- - - - -make something that bolts on and looks right, and make it work pretty well for a variety of engines. If it works exactly right, it's a fortunate accident.
