gpbeau Posted May 1, 2023 Share Posted May 1, 2023 I have a '72 with the 350 4-bbl and auto trans--stock restored. I'm rebuilding the QuadraJet carb which I believe is original (or at least date correct)--number 7042202. I cannot find a reference to confirm what jets and metering rods (primary and secondary) are correct for this carb (at least what the factory put in it). Does anyone have a reference with that info or can you point me to a website that has it? TIA! Quote Link to comment Share on other sites More sharing options...

It was a good little challenge, I can usually hunt down info quicker than that.😄 3 3 Quote Link to comment Share on other sites More sharing options...

Not sure what you're implying, but I spent two solid hours on Saturday sitting with Mr. Google hunting for references on the Interwebs for this info. Ran across all kinds of rebuild instructions with the setup specs with this measurement and that, but nothing with the jet and rod info. Yes, I posted in a FB group this morning looking for suggestions, but I did my own research and just didn't have the magic touch. Quote Link to comment Share on other sites More sharing options...

Not implying anything bad towards you at all and if it went that way I sincerely apologize. It was not intentional. I read this morning your Facebook post and you had no answers. I was more complimenting this site, and Joe, for the fast and accurate response to your question. That’s all. Sorry if it was misconstrued. 6 Quote Link to comment Share on other sites More sharing options...
Crom Cruach Posted August 5, 2023 Share Posted August 5, 2023 I also have the 7042202 quadrajet 4MV 1972. They are extremely lean from the factory, and ethanol makes it run leaner. On advice from Cliff Ruggles I changed the jets from 74 to 76, and the rods from 45B to 44B. Also important to change the accelerator pump to an ethanol-proof one. 2 Quote Link to comment Share on other sites More sharing options...
