I have maybe 60 or more carburetors in my stash.
I was restacking stuff and organizing my shed to make room for a Nova.
Now i found some Carter AFB carbs that have the venturi inlets of the 600-625cfm but the throttle blades in the primary side are nearly the same diameter as the 750's
I looked up both numbers and back then the factory did not really rate all carbs by cfm.
2982S 1960 Buick 401.
3633s 1964 Buick 401. Nail heads of course.
Now researching numbers I came across a 3636s carter AFB number online.
It is a 3 barrel made for Pontiac. 939 CFM 1963 412 super duty.
Holley later rolled out their 3 barrel carb.
