Well, while buying a set of 670 heads, intake, and what I thought was going to be the correct carb for my 67 GTO Auto car I ended up with a really nice set of heads, and intake all three with same day date codes. The carb however although from the Pontiac factory ( known for sure) has a strange number. Rather than the tag that's on the normal 67 carb this one is stamped with 7037262. Now, I had a friend look in his Pete McCarthy book and left me an e-mail saying it was listed for a 67 GTO. Nawwwww, I never heard of anything other than the 7027262 which I've been looking for since mine was stolen by the shop I was having it rebuilt at. Doors closed and everyone lost their parts. Anyone know of such a carb? If so, whats the deal with this odd number? Also, looking at the 67 Heads they don't look like my 67 heads but mine are mounted and I can't tell what not the same. thanks friends. < Mike >

not sure, but I know the California models had a different number in the part#. I believe one had a 2 the other had a 3 somewhere in the sequence.

This site show it as a 67 with A.I.R.

Thanks for the information. Well, nice carb and right year but guess my hunt continues for the one I need 7027262. even though they were not the best year for the Q-Jets it's what my car had. Again, thank you friends.

I'm building a '67 California RA if you wish to sell that Q-jet. Let me know...

I'm wondering if the A.I.R. model was designated as the service replacement in the 70's-80's. I have the A.I.R model on mine as well and it wasn't from CA. Original owner said the car had carb replaced at one point.

[carbking]

The 7037262 in fact is the carburetor for a California only 1967 400 A/T (the A.I.R. being air injection reactor or smog pump - not air as in air conditioning).

The California carbs were never offered as service units for the federal versions (calibrated too lean, need modification to run on a federal engine).

While California carbs are now almost as difficult (sometimes more so) to find than their federal cousins; about 20 years ago they were regarded as clumsy doorstops and dirt-cheap. For this reason, some unscrupulous dealers advertised them in HMN and other places as "1967 GTO" not telling the customer they were too lean for the federal engines. Since they were so cheap (about 10 percent of the cost of the federal carb then), several were sold.

Carbking, what is the difference besides jetting if any?

[carbking]

While there are many differences, the MAJOR changes are in the idle circuit. Remember that the early smog emission program only measured emissions at idle and low speed. Jetting is lean, idle and off-idle are very lean. There are other differences as well.

If I'm wrong someone please correct me. But, after looking at some applacation charts it appears that the Q-Jet # 7037262 was also correct for the 1967 California GTO Ram Air car. If this is true, then I may be a little closer to getting my none AIR 67 carb I do need. So, please keep in mind what I have as far as the 67 AIR carb. WHich is in very nice condition having been rebuilt not long ago. And, I'm looking for number 7027262 that's decent and able to be reconditioned for a nice car. Good day friends. Mike.

RR67GTO - The listings to which you refer are pulling the information from the 1967 Pontiac Master Parts Book which contains a misprint.
The following is an excerpt from the 1967 Dealer Service Bulletin 67-I-28 dated 6 February 1967:

REVISED QUADRAJET APPLICATIONS

Item 2. The 1967 GTO (auto. trans. only) with the Ram_Air option now incorporates a new Quadra-Jet carburetor, model number 7037271... replacing model number 7027262 on code XP engines only.

The Rochester Master Parts Book has specification page 9C-638 dated May 1967 stating 7037271 1967 GTO Ram Air; 7037276 1967 Firebird Ram Air.

Also, we have 7027262 carbs, although they are in restored condition (or will be as soon as we finish them).

Jon.

[RR67GTO]

Jon, thanks for the information and the reason the carb is listed wrong. I do have a question though since the engine you refer to was the XP engine. What about the A.I.R. code XS engine? Was this not a version of the RA engine? And if so, did they keep the 7037262 carb as the correct RA carb for that one engine? Thanks again, having someone with your background in such an important area of our cars is a really huge help to many of us. < Mike >

[carbking]

The "XS" engine code for 1967 was RA 4-speed federal, not California (according to 1967 Pontiac Power Train section of the 1967 sales manual). The carburetor used (according to the 1967 Pontiac Inspector's Guide) was 7027263.

Not to confuse this thread but Carbking, are the modifications you are talking about something you could do? I'm interested in getting that corrected if it's possible. Never happy with the way my car idled, and it ran hot. Sure it could be many things though. Maybe better off finding a 7027262.

[carbking]

Yes, but only if we stamp the word "MODIFIED" on the carburetor body where the number would be stamped on a 1968 or newer unit, and remove all traces of the original number.

Unfortunately, this applies to ALL O.E. federal 1968 and newer; and ALL O.E. California 1966 and newer carburetors when making modifications.

Jon.

[Sixty7Goat]

Hmmm, wouldn't want to do that. But you're saying my engine definetly isn't running right because of it, even after adusting the idle mixture screws? How would one of the new Edelbrock quadrajets stack up against what I have? As a temporary, until I found and could afford a fed version?

[carbking]

Sixty7Goat - give me a call during normal business hours.

Jon.

I dont want to hijack the thread but this will save a new post on a similar topic. I have a 67 HT HO automatic(YZ) built in dec 66. The carb that was on it when I bought it was for a 65 buick. I found a decent 7028262 carb and had it rebuilt. I can't seem to find what model and engine this carb was for originaly and if anyone could help figure it out I would certainly appreciate it.

Thanks
Gene

Gene, according to my book it was used on the 68 Grand Prix. With a 340 hp 400,code YE & YF engine codes. And, the 350 hp XH code engine. Both which were automatic transmission cars. Remember, nothing is carved in stone and new information is found all the time. This information came from a book on pontiac prefoormance. Should be a nice carb for most engines I would guess. Good day friend.
