I think this is a '67 quadrajet? "7032720" is on the back in a circle (i believe this is just a casting #)

am i correct?
there's no metal tag in that circle like i'm used to seeing with pontiacs and buicks
or rather, it's there...but the tin piece is missing


did i hear that some of the chevy ones came with a mere sticker there, instead?

I was hoping to find a better home for it than the shelf around here, so i need to ID it first - what did this come on?


thanks!

I don't have my application book here but it certainly is an early QJ based on the circle where the tag goes and the secondary dash pot. Looks to be from an automatic car judging from the secondary lock out linkage on the choke and I think the side entry fuel line suggests Chevy. The number you provided ends in an even number, further suggesting an automatic application, as does the linkage mounting post on the throttle plate arm, but there's some strange bracket bolted to the arm that I don't recognise.

SS396 might have hit the nail on the head....the item attached to the throttle bracket resembles a kick down paddle for a turbo 400, where the kick down switch was mounted to the rear carb. stud.

baron,
There should be a number stamped vertically in the carb body on the same side as the throttle linkage. It is on the flat area right above the secondary shaft. If there is no number, the carb may have been rebuilt by one of the large rebuilders, they will sometimes remive the number and use thier own tag.

I figure if it is that early, it will have the condum needle valve set-up!!

it's too early for vertical stamped number. it had the number stamped in a round tin tag placed above the primary throttle shaft. PCB67SS has it right on the tab, it's a TH400 kickdown switch paddle. that's a real 66-67 carb

what'd they come in?
worth much of anything?

any way to tell if it's a '66 or a '67?

Baron my knowledge of these carbs are limited, I have one thats very similar and its a 7027200 that I bought here in the classifieds. When I took it apart mine has a funky needle and seat (warped body) from being run without the stainless mount gasket or being over torqued, and is referred to as a patty melt carb. After some searching on the net I was very disappointed to find out that they were fire hazards, hopefully yours maybe a slightly newer version. My car came with a Holley spread bore type replacement and I wanted the original carb. back which led me to buy it. Since that time I have decided to retire my original motor and purchased a LS-6 crate motor from the early 90's thats never been run. I am getting close now on doing the swap (need a few more parts) and hope to replace the glide with a 400 turbo. Since 67 and possibly 68 chevelles did not have the kick down switch mounted under the dash I have been searching for the right factory parts for my car. I have found and bought the switch and mount bracket (there are 2 types of brackets) one for a Quadrajet and one for a Holley. I am getting ready to order the Holley kick down switch bracket as the one I have is for a Quadrajet. I still to this day have not seen an actual Holley carb. kick down paddle 396/375 installed or to be honest even a Quadrajet paddle up close until you posted your pics. These switches were also used on 67 to 69 camaro's as well. Since no 66 chevelle came equipped with a turbo 400 I would guess it could be correct for a 67/68 chevelle or a 67/69 camaro. As to price I paid (wasted a 100 skins or so on mine) but it did have the circular tag installed in the round circle so it wasn't a total waste I guess. If your carb. has the funky needle and seat I have been told they can be changed or modified, but do not know this to be factual. I was also told GM did a recall on my particular carb. 7027200, which is a late 66 very early 67 production run carb. because of related fires. To the right person swapping from a glide to a 400, the turbo 400 linkage would be a nice find (Repo's available). If you happen to locate a Holley laying around with the kick down paddle please feel free to lighten my billfold. Sorry for the rambling, and I am by know means an expert on any of this stuff....Thank goodness for the INTERNET as I have spent countless hours researching.

Fwiw, the funky needle and seat, "condum" to me, flow's more fuel that the newer design per Doug Roe if I remember right.

Fire hazard is b/c the bottom well plugs leak and cause problems so they need to be epoxied over to seal them.

And yes, the intake manifold heat passage channel has to be protected by a gasket with a SS sheet on it so the hot exhaust gasses flowing through the channel doesn't screw up the carb's base plate.

I rebuilt my stock '67's once and had everything set just right and BOY would it bellow when the back butterfly's kicked in at speed..

Talk about a hoot!!!!

And I put a later Q-Jet on my 406 b/c I flat like them...

pdq67

I also love Quadrajets and would much rather have it than my current Holley spread bore replacement. Nothing like a Quadrajet coming to life on the back barrels. The well plug problem is common on a lot of them...easy fix, but I was told its the lead looking plug right behind the fuel inlet that caused the biggest concern. I was told it was drilled to aid access for machining in the seat arrangement. I'm not sure but you maybe able to epoxy it as well if this carb. even has it? Unfortunately mine does....:confused:

Baron
Post this same question on PY's board. The Carbking, and/or Cliff can tell you what it is for. Either that, or email Jon (Carbking) directly.

Doesn't that number decode to 72 year model? 4th digit?


edit: nevermind :clonk:

baron,

All the 1967 Qj's that I've seen had the traditional dashpot rather than the style in the picture that goes over the left secondary air valve to control the secondaries. Based on that, I'd say that it's probably a 1965 or 1966 model. It "may" be a very early 1967 model.

Looks like the throttle linkage has been added to, and part of the choke linkage is missing.

Best Regards,

Mike

i saw a carb exactly like it today it is a 396 carb for 1966.

Quite right about it probably being for a 1966 396.

It's a patty melt carb due to the pressure regulated fuel inlet valve, other wise referred to here as a "condom." When the little rubber diaphragm cracks you've got a big fuel leak. Good luck finding new one! However, most rebuild kits include a conversion kit so that you can install a conventional needle and seat.

Secondly, the plug on the front of the fuel inlet housing often leaked. They did a better job of sealing those on later models. If I recall correctly, they issued a recall and installed a little bracket to keep that plug from popping out.

Mike

you can lightly peen the lead around the plug, often helps or completely fixes the problem. You'll see a lot of those cards with some sort of epoxy like JB Weld over that plug.
