    1972 Correct Number/Date Carburator

    I'm trying to find a correct number/dated carburetor for my 1972, 350/200, std. trans, built in August 1971 (serial #260). Reference books say correct carb is Rochester 7042203 but I have not seen a single one with a 1971 date code - all have been 1972 dates. Books also say 4th

    Bob, The manuel says the 4th digit is the year of production , I think that means for your 1972 is for that total year(7042203). so depending on id your early car is a Carter or Rochester carb. its either a Julian date code or a month and year date code. Does that sound correct?

      I just checked - I have a G1 date code that I bought and installed on an early November of 71 car.

      You might broaden your search by noting that the Rochesters that were assembled by Carter - which seems to be a lot of the 7042203s - have a letter and number for the date code specifying month and year.
      These are not hard to find, as I've got a spare or two for that car just in case [not for sale]. Price a few years ago was $25 to $100 depending on condition.
      They were used on a LOT of Chevrolets, so even 40 years later they are common.

      If you want to spend more, check here:



      Otherwise set up an eBay search to send you e-mails when a 7042203 shows up.

        Hi Rod. Welcome to the TDB! I notice your membership number indicates you have been on board for quite some time, however, this is your first post. Tell us about your car.

        FWIW, I also have an August '71 built '72 MY Corvette (L48/4spd), and the carburetor is indeed 7042203. It is believed to be original to the car and confirmed by judges' scoring multiple times.

        Hope this helps.

          Thanks guys. Consensus is that 7042203 is the correct number. Guess I've been unlucky and just not found one yet with a June/July 1971 date. So I'll keep looking. My '72 is mostly original, 350/200, 4-spd, convertible, A/C, ps, pb, pw, tilt-trim, red with black leather interior, vinyl hardtop. Very nice daily driver. Its been in storage the last 2 years and I'm getting it running again but its running awful - lots of backfiring and low power. So I'm trying to replace it's current large aftermarket double pumper Holley installed by a previous owner with the original carb. I've also got a '67 convertible, 327/300 that I plan to restore once I get the '72 running good again. Have had the '67 a long time and used to post frequently, but not in the last few years.

            My '72 was a September car (2641), base motor but auto. It had an original Carter quadrajet.....

              Check with Mark Smith in McQueeney, TX. 830-5601205 is he last number I have for him. I got my correct QJ from Mark about 4 years ago. My car was produced while Rochester was on strike (9/13/71), so mine is a Carter. It is a 7042203 with a G1 date. I know Mark has at least one Rochester available, unless he has sold it. Good luck. Took me two years to find mine.
