    Hello All,

    I am looking for a carb to go from 2 bbl to 4 bbl on my 68. I have read enough to figure out a QJet is the way to go. hoping for a Rochester for short money, nut came acrss this Carter #7043202. Decoding the numbers I believe it came from a 73 Chev 4 bbl auto. Needs to be rebuilt but still wondering if it's a contendor or if I should keep looking?

    I would recommend staying with a qjet that is from a Buick 350. I purchased one from quadrajet power. Mark is a member here (carmantx) does excellent work and fair priced. I have a 69 that I converted from 2 barrel. If you are looking for one to do yourself I have one for a 72 Buick 350. Hope this helps.

    I'm with Matt on this, save yourself the headache and get the carb that's calibrated for this engine - that would be a 7028244, or 245 if it's a stick car. The 244 should be easy enough to find, and you could probably substitute a 69 or 70 with similar results....Good Luck!

    I guess the hunt continues! I'll reach out to Mark and see what he has. Thanks for the offer on the 72, would have it rebuilt as I know jack about carbs. Price?

    I heard that that the early 70's QJets were a better choice (?). Wondering if it's a "Cali Only" does that make it less desirable. Asking specifically about 7041544. Saw a couple on EBay in decent shape that could be rebuilt

    That's a 71 50 state 350 Q-Jet. Good choice of carb, I was going to include that in possible substitutions but just got tired of typing. It would have the revised float geometry so yes, it's a "later" carb. Mark or Ken (Techg8) can tell you anything else you need to know.

    Good Luck!

    Lots of good advice for you. The 69-74 buick 350 quadrajet is what I would recommend. I keep cores in stock that I could build from.

    Which intake are you going to use? I see you're from Mass, so choke function may be a consideration. I am in northern CT, and prefer operational choke for spring and fall temps.

    Consider if you will use a divorced or manual choke, or if you want electric choke.

    1976+ M4M Quadrajet are more suited to electric choke conversion.

    I got one from a guy here. OEM Iron from a '72. I figured that would be the least headache. Definitely want to keep a choke in the mix!

    Not sure if I should switch threads for this question, just on a roll:pray:

    I'll be swapping out my ST300 for a TH350. Can I use the existing throttle linkage and set up?

    Can't say enough about the Qjet or the service Mark provides. I have a 68 Qjet 350 that Mark went over and his work is top notch. As for the choke, living in ten NE your going to want that item.

    Yes definitely will need the choke for a few more years! Fla after more SNOW!!! Then I'll take the choke out and smash it! LOL

    I know I'll need a new air Filter housing to go on the 4BBL QJet. Will one from a 350 from the 80's fit or does it have to be from the 70's like the carb?

    Any quadrajet air cleaner will fit. All of the carbs have the same air cleaner base. You may could find an aftermarket chrome air cleaner for less money than an original type.

    Thanks Mark! Yeah the aftermarket ones are fine until you have to figure out where to connect everything up (PCV, Valve cover vent, etc). I've had headaches trying to get stuff to run right with them. Actually looking at a set up out of an 80's Regal for short money.
