Roger on the budget! We've all been there and I completely understand. The Streetmaster with an "Aluminum Four Barrel" (AFB) will look cool and give you a real decent driver - especially if you talk nice to that ol' Carter with a rebuild kit!

You probably know that the "Chevy" version made in the 60's flows 625CFM and the versions used on the Buick Wildcat and Pontiac GTO flowed a bit more (650CFM).

The later (9000 series) part numbers are really easy to interpret as they directly correlate to the carbs flow ratings, i.e., a 9400 flows 400CFM, a 9500 is a 500CFM carburetor, and a 9625 flows 625CFM. Part numbers that end in the exact flow rating (i.e., zero or five) are designed for Chevrolet applications; adding 1 indicates Chrysler compatibility (for example, part number 9626 is a 625CFM carb unit for Chrysler engines) and the addition of 2 (9627) refers to a 625CFM for Ford.

Only the Carter "Competition" was offered in larger than 625CFM. The 9750 flows 750CFM and is easily identified as it came with either a manual choke (or in the case of 2 x 4) no choke at all..

Have fun and let us know what you decide!

Top it off with a chrome air cleaner and you'll have a good look too!
