If you're not lookin for a numbers matching Q-jet, there are lots of places to buy. If you want something similar, any '68-'70 Pontiac Q will look similar. And they are the same 750 CFM size. But, since these carbs came on 1st gen Birds and '68-'70 GTO's, many rebuilders try to overcharge for 'em.
Here's one that should be clean enuff to make a real good rebuild core. Just update with a good rebuild kit from Cliff Ruggles, and it should be good to go.
If you want one that looks similar but is an 800cfm model, you can buy an early 70's 455 Buick carb. Everyday Performance shows several of these Buick carbs.
At the time I'm posting this, Everyday shows a '71, a'72, and a '73 800cfm Buick GS455 Q-jet. Are they REALLY 800cfm ? I have absolutely no idea. Are the carbs they have, really the numbers they list ? I have no idea. There is all sorts of wrong and misleading info on the net. The carb numbers they list are 7041540, 7042240, and 7043240.
This article says the 1970 GS455 also had the 800cfm Q-jet. Is this info correct ? I don't know. I suppose if you look up enuff Buick info online you can eventually come to your own conclusion about which years and numbers of Buick carbs were 800cfm.
On page 9 of Cliff's Q-jet book, he says that the '71 Buick 800cfm Q's were the 1st 800's produced. So, I assume that means that many of those carbs were actually made in 1970, then used on '71 model cars. I can't confirm any of this, as absolute fact.
Or, if you don't mind having a later model Q, the '76-'79 model Pontiac and Buick Q's are 800cfm and have the APT adjustment, which is a desirable feature. The Pontiac models have a huge "smokestack" vent, which requires a hole for it in your air cleaner base. Or you can buy a Buick model, which doesn't have the big vent.
At the time of this post, their website shows that Everyday has a '76 Pontiac model in stock. It appears that a direct link to the carb does not work. So, to see this carb, you'll have to go to the Everyday home page, then click on page 2. The '76 Pontiac carb is near the bottom of page 2.
SMI is a Q-jet rebuilder with a very good rep. They show to have these later model Pontiac and Buick Q's. And they probably have some of the older cores also. Have no Idea what's actually in stock.
I've read some good reviews of the Jet brand Q's. Their #32102 Stage 2 800cfm Pontiac model appears to be a BOP model without the "smokestack" vent. But I don't know if the carb pictured is the actual product you'll get. The B & O model looks to have the same pic. So, you may need to buy the B & O model to avoid the big vent. It's part #32002. The price is $390 shipped, from Summit, Jegs, and other places. The best shipped price I found is about $370. The carb pictured is a #17057258, which should be a '77 Olds model.
And, of course, Ebay has lots of 'em, and Summit can order a Uremco brand. At the time of this post, they actually show that this 1st one can be shipped Mon Aug 3.
Edlebrock also made their own Q-jets for several years. You can still find some of these for sale, occasionally. There were 750cfm, 795cfm, and the #1910, which is advertised at 850cfm, which some dispute. These E-Q's are good carbs, but they do have the Chevy style, passenger side fuel inlet, which some Pontiac guys don't like. There are usually some E-Q's on Ebay.
If you want one that looks similar but is an 800cfm model, you can buy an early 70's 455 Buick carb. Everyday Performance shows several of these Buick carbs.
800 CFM will be '72 and later for the Buick 455 carbs.

Not for argument, but just to try and present correct info: lots of Buick sites say that the '71Buick GS455's had 800cfm Q-jets. On page 9 of his Q-jet book, Cliff Ruggles said the 800cfm Q's were introduced on the '71 Buick models. So, I assume that it is safe to say that some of the Buick 800cfm Q's were made in 1970, for use on 1971 models. If I'm wrong, then I stand corrected.
No, this Q is not any better than any of the other similar Pontiac Q's. But it has the correct number tag for a popular '67 Musclecar. There are certain # rare Q's that will sell for thousands, to some collectors, who are restoring high dollar, numbers matching cars.
The story as I understand it from a couple guys who do concours restorations on Buicks is that yes, some 1971 455 Buicks came with 800 CFM but that not all of them did. So, you have to check a '71 to verify if it is 750 or 800 CFM. GS455s weren't the only Buicks with 455s, the Rivieras, Centurions, LeSabres and Electras could also have them.
So, if you have a '72 or later Buick carb you will likely have an 800 CFM carb, a '71 must be checked and a '70 will be 750 CFM.
P.S. Of course my sources could be incorrect.

So, I stand corrected. Well, talked/posted with two others who rebuild carbs who both said every '71 they've worked with was 800. Someone needs to tell George that. But I liken this to the Ram Air II distributor #'s here.

Mine has a 7033676 on the base,703383 on the back, in the circle on the side it has 7262 penciled in. I rebuilt this carb and it ran my engine before I pulled the drive train. Other than that all I know is that this carb was on my #s matching 67 400 conv a/c 400 auto with yt 400 and 670 heads. any other questions give me a call352-318-3604.
The carb numbers they list are 7041540, 7042240, and 7043240.
