I just got a 2G carb off a 71 chevelle with a 350...carb # is 7041114. What size would this carb be? CFM's? Would you know if its a 1 3/8 or 1 1/4? Thanks a bunch.

Howdy all! Yep, we're out here in Iowa taking in the racing and watchin' the corn grow. :-)
That carb is a 1 1/4" venturi very common 2bbl off a 1971 Chevrolet car with an automatic transmission. It can be made into a good carb, but in stock form, they are about a 380-400cfm at the most.

Hope that helps,
KP

Thanks KP....thats exactly the information I was looking for. If I run this combination I want to...I would have to run a restricter plate.....I am not sure what size they are tho. It would prolly do no good to run a bigger 2G than this when running a restricter? The class i'm in we can run a 2 or a 4 barrel. If i move up I will have to run the 2G with a restricter. I need a little more comin off and I have my gears and tires set for the RPM i want at the end of the straights. So I want to try something with carbs to help me coming off. I am running a quadrajunk right now...not sure of jets yet. In your opinion....for stock...would you use a 2 or 4? which is better for coming off? Thanks. Carb stuff gives me a headache and prolly A.D.D. lol...so have a guy like you here sure helps dummies like me...Thank you for helping KP.

P.S. Good luck this weekend guys!!

Sorry for the delay, we've been on vacation in Iowa all weekend. If you're currently running a quarajet, stick with it, you'll never get as much HP with a 2G carb as with a quadrajet, so just tune the quad to be crisper and to get rid of the secondary bog/sag. A good healthy blueprinting usually works wonders.

cya ya all after vacation time,
KP
