72 Chev, All Quadrajets will flow 750 C.F.M.. If They are set up properly, that is, getting the Secondaries to Open all the Way. In the 80"s one Model of Quadrajet was made to Flow 825 C.F.M.. Let Me look in a Book I have, and I"ll Post it tommorrow. Also, Doug Roe has a very Indepth Book all about Quadrajets, It covers Everything.

This is the Book I"ll be Looking at Tonight.

Just email that OEM number to Recarbco Carburetors at www.recarbco.com (you have to go to their web site and click on the email link there), and they will tell you, they have a parts cross-over they can look it up in, in about 3 minutes.

Most run at 750 cfm,but besides the mentioned
825 cfmthey did have 800 and 850 cfms in the
1970's.I had an 850 on a 76 gmc 1500 truck
with a 350.

Cool

figured an 850 would be too much for a s/b, wellcontrol. thats why i wanted to find out what this one is. i threw it on my 350 and ran it for a couple of days. didnt have near the throttle response of my stock 750. i didnt really mess with it much though, i did get the mix right and the choke worked. it did idle rough a couple of times,had been sitting in this dudes garage for a while, may have a little dust in it. like i said, all i did was set idle mix and choke. P.S. thanks for the replies!
