Carter Qjet

[rx dealer]

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.

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.

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

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.

i didn't know it happened twice..

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

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.

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.
