Numbers matching?

[Spartan]

Hello all. Searched limited. Wondering if there is such a thing of Rochester qjet 4 barrel numbers that match engine year? I want a correct look from afar as well as under the magnifying glass. Thanks and... Man I love this site!

There is a way to tell if you have the correct carb. Here's a link to identifying the Quadrajet by year, manufacturer, and application.

Thanks for sharing the info ...

Here is a link to Cliff's on decoding. It has been too long for me to wing it. The actual application number can be found in the service manual along with the individual setups.

EDIT... Sorry about posting the same info. For some reason #3&4 didn't write until after I posted.

Thank you for the links and info. I just want to look for and find the factory correct carb. Unfortunately the PO misplaced it.
Cheers!

After looking at that information would it be safe to say that since the truck was born in Fremont it came with California emissions...or would they equip it differently if it was made there but going to Oregon or Washington?

So... The search begins for a "7029201" with the sixth # being a 0,1,2 and/or the seventh # being odd 1,3,5,7,9 for manual. This truck was numbered late in the production run of 69's... Awesome info, super helpful, thanks again folks!

Unless the truck was ordered by a California dealer it probably would not have the RPO K19 Exhaust Emission Control. Sometimes border state ordered vehicles will have them but not often and at the $50.60 it cost it is very unlikely.

The best thing to check will be the SPID, Protect-o-Plate and the build sheet. If your truck was built in Fremont the build sheeet or the remains may be in the seat back.

If you have or find any of these please share the information.

[Spartan]

SSTim- thank you. Wasn't sure if it was SPID worthy. It's an Oregon truck no emissions. So far no build sheet. My guess is it's a mouse nest by now. I'm second owner. First owner put 90k on it, hit a deer in 94, where it sat under its camper until a friend pulled it out of the briars a couple months ago.

In the info it says the carb could be a Rochester or carter. Is one better than the other?
Any idea on what they go for? NOS?
I learned more on this site today than I learned all last month on other sites! Whew!

Carter built Quadrajets under license from Rochester. In my opinion, one's not really better than the other, but I'd probably look for a Rochester if you're going all original.

As for cost, local cost (and condition) will vary widely. I know you can get a rebuilt Quadrajet from Summit for about $300.

[Spartan]

Truckster- that's what I figured. It's a good start. Unless summits rebuilds are numbers matching for me I'll probably keep trolling til something comes around. As always a am greatful for info and opinion of those who know these trucks.

Here is a link that will take you to the info you are after, second post halfway down. Lars is a "Quadrajet Guru" and the info found in this link is very useful.

I have an original Quadrajet off of a 350, came out of a 1969 C-10 shortbed, it's still on the motor, all original and was still running! I can't find any numbers on the sides of the carb...I could take some pics in the A.M for ya...

[Spartan]

First I want to thank everybody. Loads of info. I went out to the storage shop and took a look at my 69 gladiator which has a Buick 350. Behold!a Rochester qjet. It's fitting because the jeep is analogous to the k20 - same truck different manufacturers.

#'smatching- I would appreciate pics. Specially if it's still on the engine. Iirc from the pics I saw earlier the numbers are on a machined area drivers side. However, after typing that I will say I have been reading so much that I'm feeling a bit scrambled and may have confused driver side with passenger side.
Cheers!

Might want to check out Judd's (Vintage Windmills) build. He is restoring a '72 K20 and there is a lot of information there. He had a Quadrajet rebuilt with an electric choke update that you might be interested in as well.

Judging by what the link to the Q-jet guru says, mine must not be right, or I don't fully understand what he's saying...It was suppose to be on the drivers side of the carb by what I understood...I found a steel tag with the #'s (weird stamp) then #'s 29865 on the very back of the Q-jet...Which isn't even on the chart...his number chart shows: #7029223 CHEV 69 350 TRUCK M/T Don't know if this helps or hurts!? Hope you find what your looking for...

[chipflyer]

No idea what you have, its not a Rochester number. The photo shows the location of where you would find the carb ID number. Typically when you go to a parts store and buy a carb that is "re-manufactured" they will add the little metal tag to it as you describe with a number that means something to them. I have never seen a reman that had the original number on the side removed.

[chipflyer]

Here is another good resource for looking up Quadrajet numbers. Hope this helps clear things up.

Thanks for the pic and info Chipflyer...It's just to dirty to see! lol Ya learn something new everyday! The #'s on the side read as 29224 QB 1749. Here is a pic of the dirty old girl...She ran, but I doubt it was like she was suppose to! lol

[Spartan]

#'smatching - if the tag is round I read that it's early Rochester.
...and gosh everybody thanks for the links. Really turned out to be informative. It doesn't look like it will be difficult to find the correct carb. Any 69 350 m/t will be close enough until a perfect one surfaces. I might go take the one off my 76 formula or the 85 custom camper beater sitting in the back 40. Shoot my el camino might even work since it has a crate with all the comper stuff deleted. I'm so caught up restoring my 73 cj and this k20 I wasn't even thinking of all the options. Still, stock and correct being the goal.

Thanks again,

Nim

#'smatching- thank for the pic. Nice OG intake. I'm guessing by the numbers it was in an auto?
If knowledge was dollars this site is certainly a wealth.

Love those old jeeps too Spartan! Here is my 86 J10. Clean, original rust free truck, has a razor grill now.

[All#sMatching71GMC]

Thanks, I bought the whole motor from the original owner. Most definitely a wealth of information shared on here! I thought I knew stuff about these trucks, until I came to this place! WOW, the info and the trucks are insane! Correct, about the numbers...the guy I got it from let me part the truck out, the tranny was already gone, I don't know if it was a 350 or 400, could've been the reason it was left to die. But what the rest of the numbers QB 1749 means is a mystery to me...It wasn't in the gurus chart, unless I overlooked it...I'm guessing jet sizes? lol I'll bet chip is shaking his head at me right now, cause he knows exactly what it means! lol
