Probably 800, - doesn't really mean anything, as the Qjet carb is designed to only give the engine what it needs....so if your car only pulls 510cfm at WOT then thats all it will get, because of the secondary airflap.
So cfm rating when running a qjet, isn't really an issue.
There's a way you can tell if you have a 750 or 800 by looking at the venturi's.. i think its the primaries...- the tip can be found on google- if theres a full ridge around the venturi's its a 750 if there's just a hump then its an 800.
