Quadrajet for 1969 350/350

[James A.]

Do the numbers look correct on this photo for a November 1969 350/350 4 speed? How about the leading 0 and the punch marks? Thanks in advance for any help.

Looked good in the preview, I'm trying to figure out what happened.

It looks a bit strange to me. At least, I can't say that I've ever seen one like it. One thing that's missing is the broadcast code which usually is seen in suffix to the part number. However, it may very well be an original stamping. During that era Q-Jet carbs were being manufactured by the "zillions"; there may have been many variances.

One thing to keep in mind, though. This carburetor part number was manufactured for MANY years in SERVICE and used to SERVICE all 1968-69 small block applications, Corvette and otherwise.

Since I posted the photo I looked up the julian date in 1969 and it is on July 19, 1969 which is a Saturday.

James,

I'm no expert by any means but I have a feeling that it may be a 79 instead of a 69 carb. Try and post some pics of the front of the carb and I might be able to help you out.

I agree that it is a service dated carb. They did sell a ton of these over the counter.

I'm trying to find the right carburetor for my car and this one is for sale. I think I'll pass on it and look for another one. Here are photos of the front and sides. What should I look for other than the numbers and date?

James,
I've been looking for a correct 7029204 FF carb for about three years now for my Jan 31 built car. During my search I noticed one thing that generally stood out between production q-jets and later over the counter q-jets. If you look at original 7029202, 7029204 or 7029207 carbs they are "missing a feature" that the later service carbs have.

The restored one on the left is a 1974 7029207 carb that I was going to use untill I came across the correct 29204 FF carb on the right. Notice the raised triangle shaped casting with a "hole" in it on the drivers side front of the main body which the 204 carb doesn't have. I don't know when this raised triangle piece was incorporated but I've never seen a real 69 carb with it.

I also just learned that the fonts for the p/n and date also changed sometime in 69 or 70.

Here is what the font's look like on my Dec 26-68 carb. This style was used until at least late May-69.

This isn't a corvette carb but the fonts are the same. This is from a early 1970 carb and it has the same fonts as my service 7029207 in the previous pics. Note the differences in the "0" and especially the "4".

I don't know when the font change over was or when that little triangle piece was first cast into the main body as I wasn't really researching this. These were just observations that I noticed while searching for the correct carb for my car so it's probably pretty safe to say that a production 7029207 carb should NOT have that raised triangle piece on the body and it should probably also have the older style fonts. I say probably on the fonts because you have a very late 69 and I don't know if they were still using the old fonts or if they had switched over to the new fonts by that time.

Oh and for what it's worth this info is only for the Rochester q-jets. I haven't seen enough of the Carter built ones to comment on them.

Hope this helps.

Re: Quadrajet for 1969 350/350

Thanks for the help. The carburetor I have now is a service replacement with the triangle. It has a 2815 date. I'll keep looking.

Re: Quadrajet for 1969 350/350

It's a later service replacement, possibly 79 or 89.
Note the "0" at the front of the part number - that's what identifies it as a service replacement.

Re: Quadrajet for 1969 350/350

that triangle with the hole is where the screw went in the later ones to hold the solenoid in place

Re: Quadrajet for 1969 350/350

Patrick,

I have read that the "0" did not come about until the 1980s as this is when they were produced for NHRA racing. A '78 or '79 dated carb should not have the leader "0", which makes identifying the stop solenoid the easiest method of determining if the carb is a service replacement or original. Also, the carb should have a "DA" broadcast code identifying it for a 1969 L46.
