Nothing in the original factory literature for my 300F (including owner's manual, service manual, parts manual, service bulletins, and advertising and press kits) indicates the CFM rating of the carburetors. Apparently this was something that the design engineers didn't think the owners or service technicians needed to know (and why would they?). HOWEVER, later Carter AFB's with identical throttle bores and identical primary and secondary venturis are rated at 625 CFM (see Dave Emanuel's book on Carter Carburetors). Therefore I think it is a reasonable assumption that the earlier identically-sized AFB's had the identical flow: i.e., 625 CFM apiece. This would be true for the 1960 300F and the 1961 300G. Might be true for other years, but I don't have the carb dimensions for 1959 and prior or 1962 and later. 300F'ly, Roger Karlson ************************************** See what's free at http://www.aol.com.
