Can't find info on the number on my Q-Jet

[Quadrod]

29231    1769

Believed to come from a 1969 Cadillac 472

It does say Rochester Quadrajet and there is no round ID tag. This is stamped into the side of the carb like all other number locations I've read about, there's just no "7......" like I've heard that most do.

I need a rebuild kit but need to know what to order.  Thanks for any and all help!

Just received your book BTW! Great, and will definately aide me in the rebuild of the above carb, just couldn't "ID" it from any info I've found. Thanks

 Probably 7029231.

 Which is 176th day of 1969 Cadillac 472cid M/T Air Conditioning

Thanks, I've heard of just assuming the 70 was left off, but then the issue of the M/T comes up. Cadillacs were all automatics. I want to make sure that I'm getting the correct rebuild kit. I really don't like guessing with money.

Thanks for the reply Ehtan1

 You are correct. Since the last number is an odd number, it would be a manual transmission. I looked in my other manual and it shows '67-'69 Cadillac 429cid and 472cid engines automatic transmission. Maybe someone can shed some light on this? I've seen this before on a nother Qjet. Don't know the reason, but Cliff will have your kit. Can you post a picture of the entire carb? Just to be sure.

 Also, if you look on page 16 of Cliff's book, it says that there is "numerous" exceptions to the last number being an automatic or manual transmission. So, maybe Cadillac was one of those exceptions since all were automatics. I don't know. Let's see what Cliff says.

Thanks again for the help I'll post a pic of the carb a little later. It's actually disassembled now but I'll stack the three and do my best:) I'm definately going to buy the kit through here as soon and I know which one to order.

Glad you've seen numbers like this too before. I was thinking I was the unlucky ONE to have something not rebuildable ha ha

Glad we're getting to the bottom of this

 Quadrod,
 I also have a Cadillac carb. Number 7028231. Also ends in a odd number. There is other Cadillac carbs I have seen like this. Don't know why. Must be a Cadillac thing.

Here are the pics

And the back...

And top views...I'm pretty sure we're looking at a 750cfm. Thick outer ring and no little bump in there.

[Ethan1]

 Yeah, it looks like the 7029231.

 Yeah, probably 750cfm. If no bulge in primaries, probably 750cfm.

Nice! OK, so I guess my next step is looking for a kit with the 7029231. Thanks for the help
