BB 69 396 L34 Carb 7029215
« on: May 01, 2017, 03:13:14 PM »
What do you guys have to say about this carb? There doesn't seem to be a date stamp on it which would lead me to believe it's an early 69 version, but there is also no date on the base plate. That could have been replaced, but I thought the early ones had the part number more centered (7029215). This one is stamped like it was going to get a date stamp, but it was missed or forgotten. Is that possible? Ever heard of it?
My understanding is the "R" stamp in red meant it was an assembly line piece. It looks pretty original to me, but I'm no expert. What do you think about it's value?

Thanks for any comments.

Dave, is that the same carburetor from THIS THREAD?

I've never heard that before and I've seen a lot of original carburetors without a red R, so I doubt that's correct.

But I'm also wondering if those base plates with the funky stamp are service replacements. It "could" be (not saying it is, but COULD be) some kind of inspection stamp for the base plate itself. Just another mystery we'll probably never figure out!

As for value, that's hard to say. It looks complete but worn, so it would have to be restored for sure, and that's going to cost a few bucks! Are you looking to buy it or sell it?

Thanks Ed. I did buy it. I knew it would need a resto, but I liked the fact that it all seemed pretty original. Even with a resto, I should have less than $1,000 into it. I keep seeing them for $1,200.00 +. The Corvette guys keep killing the price on me lol. If I can find one with a decent date for my 69, I'll just flip this one. If I find someone that wants this one, I'd probably sell it too.
There were a couple of things missing on my original motor that I've been trying to replace over time. The carb was stolen off the motor back in the 80s from my backyard. The motor is just sitting in the corner of my garage under cover, but I'd like to have all the details complete if I decide to put it back in some day.

I went back and looked at some comments about the carbs and it said the "EH and the R were assembly line pick codes." Has anyone seen any known replacement carbs and did they have the EH stamped?

Dave, EH is the broadcast code and that's what was used as the "pick" code. This is listed on the Chassis Broadcast copy under box 155 (1967 and 1968) or box 176 (1969). See example below for a 1967 Camaro SS-350 (DH code).

Where did you read about the R? I see no reason to stamp a carburetor with a red R since it would already have the broadcast code.

Yes, later service replacements could still have the broadcast code stamp, but most don't.

Dave you should have taken me up on my offer for that Quarajet from a Chevy pickup that was date close to what you needed.  Wouldn't have had the right numbers - but it would have looked original from 5 feet away - and it might have been a whole $25 plus shipping.  :)

I just noticed you asked if it was the one from the other thread. It was.
The info I got on the R, was something over on Yenko.net. I'll see if I can get some info about where they got their info from. Might just be internet info...

Thanks Bryon. I appreciate that, but I have several including a 7029201 that's nearly identical. This was just a case of me wanting the correct numbers in case I wanted to go full tilt original resto someday.

does it have the plastic choke fast idle cam lever?
I see the plastic lever on original assembly line Q-jets but replacement carbs have a metal lever.

Thanks Joe. It looks like it has the plastic lever.

Dave, looks like yours was never modified for the 69-C-6 PRODUCT CAMPAIGN! That black cam "should" have been replaced with the 7038844 blue cam. Or IS it blue and just turning old? From the picture it appears to be black, but that could be due to the age of the cam, my monitor colors and my crappy eyes!

Awesome info Ed. Thanks! It's definitely black. Makes this even more odd to me that it doesn't seem to have a date stamp. I'm sure it's possible the base plate was swapped, but the "patina" of it is nearly or is identical to the rest of the carb. I would think it strange to have changed that out and not have the cam fixed also.
Without question, this one is very early it seems.

I just got some new info. Here's what the original commenter said about it. Seems legit, but I don't know how you'd confirm it without talking to someone that was on the line at Rochester?

"if you have both in your hand, its hard to tell..but if you read the side of the carbs it either says "rochester quadrajet" or "quadrajet by carter"...
since GM used both Rochester and Carter q-jets..the big R is an identifier to help assy workers to choose the right carb for the application ..its not either or..its to choose the correct one and how that was determined isnt clear..or no one has told me in a way i that ibelieve it"

No, that's not correct. The guy on the engine dress line could care less if it was a Rochester built Q-Jet or a Carter built Q-Jet. He grabbed a carburetor based on what was indicated on the chassis broadcast copy (EH in this case), and installed it on the engine. A big red R would mean nothing to him.

I've seen a TON of original Q-Jets over the years and can't remember see ANY of them with a red R. A better explanation would be that it meant Rebuilt or Refurbished!

I dunno Ed. I've seen a million qjets too, but not too many early 69s. I'm just wondering if it has something to do with it being such an early 69 carb. I guess it really wouldn't be any different than a 68 though. Maybe it's R for refurb, but how would that work with the fact that it has the black plastic cam? If that means it's a production line piece, I seriously doubt they're putting refurb carbs on production cars.
Something to also think about. The carb would have to be disassembled, or at least the carb linkage would have to be off, to be able to stamp it where it is.
