    So, I'm looking through my box of Buick parts for my spare Q-jet, thinking it might be bigger than the stock one on my 68 gs. When I checked the numers 7041242, it come up as a 71 Stage 1 unit. Is this really one of those $1000 carbs?

    7041242 is a 71 Stage 1 carb, but the value will depend on the date code. If it is an original carb dated in 1970 or 1971 it will be worth more than a replacement/NOS carb dated months or years after they stopped building the 71 year model Stage 1 cars.

    The 70 Stage 1 carbs are the ones bringing the big $. I'm certain an owner of a documented 71 Stage 1 who is missing their carb will pay good money, but there are not that many 71 Stage 1 cars that have documentation.

    Post all numbers and letters that are stamped on the bowl next to the part #, or better yet try to get a good pic and post it. That will tell much more about the potential value.

    thanks for the reply, all I can see now is the # 0644 next to the other #. it's pretty dirty, and I left my camera at work, trying to doccument my engine R&I so I can put it all back together properly, LOL

    If it reads 0644, that would be the 64th day of 1974 or possibly 1984. If so, it is a service replacement carb. That will hurt the value if someone is searching for the correct date coded carb.

    Good luck. Post a pic when you can. :TU:

    Thanks for the info, I'm sure it must be 74 as I've probably had this in my box since 84 or so, I guess I had better dig out the heads I got with this thing and take a look at them.

    As far as I know, there have only been two 1971 Stage 1 carbs that have sold on ebay recently (January 2008).

    I think they both sold very cheap, and the new owners are probably very happy with the deal they got. Here are the links to the auctions if anyone is interested:

    The first one was an original carb dated 2040 (July 23, 1970) that sold for only $400.

    The second one was a Delco rebuilt service replacement dated 2049 (July 1979?) that sold for only $281.

    I don't know of any that have sold here on the v8buick board for comparison. You will get more exposure if you ask the same question in "The Bench" since more people read/post in that section.

    I hope that helps.

    James, thanks for the info, it was very helpful.My ebay and board search turned up only a little.I was just thinking about using a 800 cfm vs a 750 on my warmed over 400(small cam, headers ,B4b) and didn't want to play with a carb that someone else might need. Being a replacement carb, I guess I don't have to worry about that. Any thoughts on whether an 800 might be too big ?

    In my opinion, an 800 CFM Quadrajet would work very well. Big block Buicks like big carbs. I think all the 72 and up big block cars used the 800 cfm carbs. Apparently some of the 71 carbs were also 800 cfm, so maybe the service replacement you have is an 800. Check the annular ring in your primaries to see which one it is. Here is an article with pics that will help you determine which one it is, just scroll down to the bottom for the pics.

    If yours is a 750, there is a list somewhere here on the board of the carb #'s that are the 800's, and you can usually get them pretty cheap on ebay (around $75 depending on condition). Once you find one, I would recommend having John Osborne rebuild it for you. He can make a Quadrajet perform very well and builds them based on your application like cam specs, compression ratio, exhaust type/size, ignition, etc.. They really are good carbs when tuned properly. Good luck!

    Thanks for the link, for some reason I thought 71 carbs were also 800's. I've got the stock carb for my car and will compare it to that one.I will probably use that one, as I know it works and thats what is suggested for starting a fresh engine.

    All 71-74 Buick 455 carbs are 800's

    They must have made big run of NOS carbs in 74. I have 74 built Stage-1 carb as well.

    thanks for the reply Larry, when I compared it to the 68 carb the venturi ring looked similar and I didn't notice any bump,I thought it to be a 750, but I will gladly take your word for it being the larger version.
    As this is a fairly common carb, I assume it's the style that Mr. Osbourne no longer rebuilds?
