Carter Qjet
 

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.

Re: Carter Qjet
 

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.

Thanks Jesse, good information to know.

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

Re: Carter Qjet
 

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.....

Re: Carter Qjet
 

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.

Re: Carter Qjet
 

Delco-Rochester could not meet production requirements when all GM divisions converted from AFBs to the Qjet in the 1966-67 era. Carter was contracted by GM to produce Qjets for them.

Re: Carter Qjet
 

So.....could the "inferior material" have been a form of sabotage???:cool:

Re: Carter Qjet
 

Anything is possible in an industry full of union problems. I had a 71 Monte Carlo, 402/300 horse with the correct number carb on it for that engine,#17041202, made for GM by Carter Carburetor Co. Everyone said not to use it on a stocker.

Re: Carter Qjet
 

when was the rochester strike (when carter made q-jets, too)?

i didn't know it happened twice..

Re: Carter Qjet
 

Listen to what this man says. If anybody knows Qjets, Dean would know this.

Re: Carter Qjet
 

For what it's worth, I have built quite a few of the Carter manufactured Q-jets. Yes the metal does seem softer and it is a little more difficult to work with (drilling, etc.). But in my experience, I have not seen any of them to be a problem. I own one of each, and they both run the same on my car. To add to Rich Aceves' point, I have not seen any true advantage to equally prepped Rochester, Carter, or Edelbrock Q-jets. They all have variations that can lead to some cores being faster than others, regardless of manufacturer. Unfortunately, the only way to tell how fast a particular core is going to be is to build it and take it to the track.

Re: Carter Qjet
 

It had to do with volume requirements, not a strike.

Re: Carter Qjet
 

I am going to type a paragraph from my book regarding the reason GMC made this deal with Carter. The title is: Carter- built Rochester 4-barrel carburetors. "Although it may seem strange, Carter actually built a select group of Rochester carburetors. The reason is simple: General Motors needed a second source from which to buy in case of a Rochester strike. Carter also built carburetors for many other GM divisions. It is interesting that Carter built only the Quadrajet.The following listing is to date the only complete listing for all Carter- built Chevrolet carburetors. All Carter-built Quadrajets will have "MFG by Carter" cast into the carburetor body." The listing actually shows that in 1965 they came on passenger cars with the 396/325 early and late editions with automatic and standard trans. In 1966 they expanded to the smallblock 327/275 and also the 427/390. 1967 had the 427/385 and the 350/295 included. In 1968 they came on the 327/250 as well. It goes on and on.. An interesting topic. I'm glad I have one.

I had a 68 Pontiac with a 396 (that really mesured as a 402) and a Carter Q jet . A factory Canadian car.
