Carter Qjet

Jesse Knapp · 08-25-2010, 10:54 PM

I have this carb. I pulled it off a 1967 327 (803 manifold) and was wondering if anyone could share some light about it. I understand GM bought them from Carter as well as Rochester for a time. It looks exactly like the Rochester..is it? Do they perform as well as the Rochester? Just wondering since I have not seen one in a racing application. Thanks in advance.

Rochester, Carter, Edlebrock, each one has there pro's and con's, but when it comes to Q-jets if your smart try them all because its all about the core.

I'm sure someone will correct me if I am wrong on this, but I don't think Carter was building any Q-Jets back that far. They did them in the late 70's and early 80's from what I have seen. If it is a Carter, it should say so on the side.

Jim, I had one that was about 71-72 vintage, which is when I thought they were produced.
It worked okay ,but seemed to be a softer material. Would strip the threads easier.

Thanks Mark,

I didn't know for sure when they started making them, but I didn't think it was as far back as 1967. Like you my experience with the Carter Q-Jets is that they are not as good as the genuine Rochester stuff, which IMO is the finest carb ever made for surface transportation.

My information book, Chevrolet by the Numbers (1965 through 1969) shows a photo of a 67 model Carter built Qjet. Under that photo there is wording that says... "1967 Carter - built Rochester Quadrajet # 7027203 identification tag, with an M6 date and a DZ customer code." Mine has Carter written on it and on the side it has Quadrajet stamped there exactly like the photo. Also has... MFD. by Carter Carburetor for GMC as does the photo. My book shows a listing of this carb. from 1966 through 1969 available on camaro, chevy II, chevelle, and passenger cars. Book stops at 1969 model yr. I agree the Rochester is a great carb. Just wanted to know about the Carter. Thanks all for responding.

I have a 69 camaro indy pace car with the original 350-300 hp and it has a carter Q-jet... Luke SS 311

I agree with Mark.....the Carter built Q-Jets were made from softer inferior metal and the screw holes just disintegrated. I would call it more like what most people called pot metal. I rebuilt a lot of carburetors in my garage days and when I saw one of those Carter built Q-Jets I considered them junk.....

Thanks for the info on the metal. I wasn't going to rebuild it, just wanted it for parts. I was just curious about them as I'd never seen one before.
