It should be 4,1/4 inches, same as the 383`s. I don’t know if there ever were more than two sizes for the 4 barrel Carters. AVS and Thermoquads were were about 5 inches.Can someone tell me the air cleaner base diameter on a 67 440 hp AFB?
No. His original AFB is 41/4 inch , you will need the 5 inch base. His original carb is a 750. All he should need to do is get it set up properly. My humble opinion. If the price was wright, I sure would take the AFB.Reason I asked is a friend of mine has an original "real" survivor 67 GTX console 4-speed with original AFB installed. The carb has recently been rebuilt but is lacking in performance. I suggested installing one of those new Edelbrock 650 AVS2. I had done that exact same change on my 64 426 and was VERY happy. I'm guessing his original air cleaner base will still fit the AVS2 carb air horn. Thanks for the replies!

What does "performance" mean to you? Power?
The non Califorina 67 440 AFB, 4326s and 4327s, are very good carbs. They are 1-11/16" throttle bores and would be considered 750-ish cfm. Hard to imaging a 650 AVS would perform better.
If you insist on replacing the original carb, the only carb I'd consider as the next step up from factory would be the 800 cfm AVS.
The 4326/4327 carbs should fetch pretty good money.
It is the original Performer Series 1407. I ordered the electric choke kit for it as well.Is that the AVS2 or the original Performer Series?
