I think it was also used in some HP engines destined for California. Anyway, I am still in the dark in terms of cfm, but my guess of 600 is still a reasonable estimate. This engine will probably love an extra 100, or 150 cfm. Thanks all for helping. I am not selling this carb. It is destined to go to the black LeBaron and replace the Rochester. I can do it only after I find a higher cfm replacement for the green car, and after I find a suitable intake manifold for the black car (it now has a 78 iron manifold, presumably replaced in order to fit the Rochester, I will replace it at some point with an Ederblock, so that the AVS will fit).
