Post subject:  Carter Carb cfm

I have searched the carter web site and also this one and found a lot of info. on the 3083s carburetor but nothing on the cfm rating. Just curious, we are in a blizzard here in the mid-west with time on my hands

The Carter 3083S is the 4 bbl. used on the Hyper Pak, and as far as I know also on the first high-performance 273.
Quote:
Specific airflow ratings for early AFBs are not readily available since Carter did not flow rate their products in those days. However, judging by venturi and throttle-bore diameters, it appears that the flow range of original AFBs is between 450 and 625 cfm, with variations dependent upon the original application.
There is an approximation of the flow, based upon the size of the bore and venturi diameters, at buickperformance.com.

Olaf thank you for the info. I hope the metering rods and jets are ok and I can have it rebuilt with just gaskets. It has been setting in storage for 40 years

I have a couple of other AFB links here too:

www.mymopar.com/downloads/carterafbtuning.pdf

Here is the imperialclub.com's info on the AFB.

Here is a link to a thread, that among other good AFB info, lists the jet and metering rod sizes and numbers for Carter vs. Edelbrock, over at v8buick.com

BTW, 40 years is an excellent age for a carb! :lol:
