Carls right, number will be cast on the back runner like this 65 manifold. You can see the date code below as F215 in this case. That would be F for June 21st day of the month 5 for the year. Take a pic if you can. That would also help.

And please don't do like so many guys who I've tried to help identify a Chevy intake. They come back with the number 18436572!!!! (The engine firing order for those who don't know!)
Actually, likely underneath the coil you will have the date code. In your case, if it's a June car, it will likely be something like E 20 6 or E 20 66 for May 20 1966 for example.
Haaa, it'll take longer than spring to sort out what I've got going! Re the firing order, thanks for saving me the embarassment! So is it simply a date code or am I looking for either 3931575 or 3888886 marked somewhere visable? thx
I'd say copy everything but 18436572! And yes, the 7 digit number will be visible elsewhere.

Carter built quadrajets: Carter Carburetor Company of St. Louis produced millions of quadrajets under license from GM from 1966 through 1979. These carburetors carry the exact same identification as their Rochester counterparts, and parts are directly interchangeable. Carter also produced "aftermarket" replacement quadrajets, which will be identified by the traditional Carter part number (4 digits, followed by the letter "S"). An example of this numbering system would be 4675S, which is identical except for the number to 7028262.
Carter AVS carbs appeared in 1966 on the 275 HP version of the Chevrolet 327, but were never again used on Chevies after that. AVS carbs were found mostly on Mopar applications from 1968-1971. The most sought-after AVS carbs are the 800 cfm models found on 440 CID motors.
Recently, Edelbrock has been marketing the Thunder Series AVS carburetor, again reproduced by Weber USA.
Carter did not build a performance version of the AVS after OEM production in the 1971 model year.

i have been looking at carbs and the one on the 66 sd 275 hp car was a carter for sure, the gas inlet was on the back on the passenger side, this was a untouched 66 275 hp sd car .

I agree with you Carl, I just can not see them using a Holley. Good thing he did not purchase a Quadrajet carb as would not fit on this manifold. Just wondering what carb is on there now ?
I pulled down that AVS I squirelled away, wire brushed it off,, It is 4401S J7 , intended for a 68 Chrylser 383. I was clueless that chevy ran them...so now I know !!

The original was swapped back in '87. I have no idea what it was...

Man, you guys are good. It currently is indeed a replacement Carter 9625 (see attached).
Are there major differences between the Carter 9625 and the Carter AVS?... thx

here is an explanation of the differences...mostly how the secondaries work
Carter AFB for Studebaker
The Carter AFB (Aluminum Four Barrel) was the second four barrel carburetor produced by Carter, after the WCFB. AFB's appeared in 1957 and were used as original equipment on most makes of car at one time or another up to 1971. The last notable OEM application was as a dual-quad setup on 1971 Dodge 426 Hemi engines.
Interestingly, some Ford AFB's weren't made of aluminum at all, and were in fact cast out of zinc.
Carter AFB's were produced as the Carter Performance Series carbs until 1998. They are currently available as Edelbrock AFB carbs, which are produced by Weber USA. Most parts, including tuning parts like the jets and metering rods are interchangeable between the original Carter AFB's and the currently produced Edelbrock carbs.
Carter AVS - Dodge
The Carter AVS (Air Valve Secondary) is a refinement of the basic AFB design. Whereas the AFB used a velocity valve, which is a counterweighted flap below the secondary venturi, the AVS used an air valve, which is a spring loaded flap above the venturi. The purpose of the two is similar, but the air valve is adjustable from outside the carb.
When the throttle is opened so that the secondary throttle plates begin to open, vacuum develops under the air valve, slowly pulling it open. In this way, the air flow is controlled and the mixture is kept from getting too lean if the throttle is opened suddenly.
Carter AVS carbs appeared in 1966 on the 275 HP version of the Chevrolet 327, but were never again used on Chevies after that. AVS carbs were found mostly on Mopar applications from 1968-1971. The most sought-after AVS carbs are the 800 cfm models found on 440 CID motors.
Recently, Edelbrock has been marketing the Thunder Series AVS carburetor, again reproduced by Weber USA.
Carter did not build a performance version of the AVS after OEM production in the 1971 model year.
the original carter AFB 9000 series had three basic models with part number cast in one of the front feet (I think it was on right side). 9400=400cfm, 9500=500cfm, 9625=625cfm. if the carb part# exactly matches the basic part# then it's setup for chevy linkage. if the last number is 1 greater than the basic part# then it's setup for chrysler linkage. and last number is 2 greater than the basic part# = ford. e.g. 9625=chevy 625cfm, 9626=chrysler 625cfm, and 9627=ford 625cfm. the other twist to the part numbering is adding 10 to any of the above examples indicates EGR provisions. e.g. #9637 ford 625cfm w/egr.

The J7 is a date code September 67 . Would fit right in for a early 68 car.
Looks like Geof's carb is a 625 cfm (9625) date H9 August 69 or79

Thx again for the insight guys. Other than going for originality, any thoughts as to whether or not I should try to locate an AVS?
Re the 625cfm... I read once where it was mentioned that a guideline for carb cfm is a calculation of displacement times max rpm, then divide by 3,456. (If I use the 327 max HP rpm of 4800, the calculation recommends a cfm of 454.) Any idea of the cfm of the AVS?
(I'm thinking that this might explain why it seemingly launches in the higher RPM's. I'm thinking I may have a little too much carb?)

Just noticed this in the light blue. So the one I have is correct for a Chevy? That's good news... thx

it is for a chevy, BUT there is a pile of tuning that can be done to them. go the edelbrock site , should give you some info and guidlines for what jetting and so on.
we played with a AVS on big cam application,,,made quite a difference...

Back in '66 two friends bought new 327 275 hp Chevelles, Oshawa built. Both had the Carter AVS (Air Valve Secondary) carbs. I put the same setup on my 283 Beaumont and it worked fine. Sure was no match for the 327s though.
I am not doubting you at all Keith. It is just so strange that I've seen a number of Canadian 327 cars for 66 and never seen an AVS on one. It It makes a guy wonder if the early/late listing in the parts book is totally correct. It's very obvious they made them, and likely lots of them.
It can't really have anything to do with the area of the country the car is sold in, because cars move around. If I hadn't seen it in the parts book and see you guys talk about it on here, I would have said there is no such thing.
When I was just out of high school, a friend had a 65 Parisienne 2 dr ht 327 with a Carter. That would have been a 300 horse. That's the only Carter 327 I ever saw that was factory.
