Q-jet ID help

I'm trying, with no luck, to ID a Rochester Q-jet. The roll stamped numbers are 24291ME 1229. Any help would be appreciated. It has a center fuel inlet and what appears to be carb linkage that would use a rod to activate the kickdown feature for a TH400.

Thanks,

Ed

You are missing a few numbers it looks to me (24291) ME 1229 Anyway the ME is the two letter code for a factory installed q-jet (VS one purchased over the counter). 122 day of 9 (for 1969)

Or try this website: http://www.recarbco.com/technical/rochester/qjet.html
Here it sez it is a 1964 carb, assuming there is a 70 or 170 in front of the 24291. Post a pict of the numbers.

 

Dan,

I was all over the carb looking for additional numbers and couldn't find any but the few that I stated. I've searched the web and I have both Cliff Ruggles' and Doug Roes' books on Q-jets but I can't find anything anywhere; that's why I finally came here hoping perhaps someone might know about this odd number.

It couldn't be a '64, the first Q-jet wasn't introduced until 1965 on the Chevy 396.

Like I asked, get a clear picture of the numbers so we can see what you are talking about.

 

Post or send me a pic of the carb. I can smell it from across the room and tell you what it is!.......LOL......Cliff

 

Cliff, I'm posting pictures for you to sniff.

Dan, The roll stamp numbers are exactly what I posted. Perhaps you'll read them differently than I did.

Cliff, I'm putting a 200-4R transmission behind my nailhead and running a '66 nailhead intake with a Qjet. I need the piece of linkage off of a Q-jet that connects to the throttle linkage and the TV cable. Can I just replace that single piece on the Qjet I have, or do I need to replace the entire throttle shaft from a carb that was OE for a car equipped with the 200-4R?


Thanks in advance.

7029241, 69 Buick carb, and it appears unmolested with all of it's original components.

We can remove the big "hook" and put any type of linkage on the stock shaft and MIG weld it in place.

This opens up limitless options as many later years used TH350 transmissions and in the 80' the 4L60's and 200-4R's, so any of those can be used on the stock 69 shaft.

I've even just added the needed part to the stock linkage for a few Buick folks to use transmissions requiring a TV cable.......Cliff

 

Getting dyslectic with the I.D. numbers will burn you every time Ed.:laugh: :beers2:

 

Cliff,

Thanks for the recommendations. I'll start looking for a carb from from an Olds or Chevy V8 that was connected to a 200-4R from which I can get the piece I need.

Cliff and Dan,

Any known reason why the 70 was not part of the stamped numbers?

Made by Carter???

 

OEM units used round tags till early 1968, then they moved to a rolled stamping on the casting. The first units used the entire number followed by a Plant Code (Rochester), the Julian date was on the drivers side of the throttle body just behind the secondary throttle shaft.

I'm guessing when they finally decided to move the Julian date to the main castings, they set the first units up to be stamped all in the same line, so they had to omit the "70" to have room.

We quickly saw the Julian date moved and the "70" put back on the castings. It was usually just below the Plant Code on the Rochester carbs.

There are exceptions to this, as they used smaller case letters and did have the entire part number, Plant Code, and Julian date on the same line in 1968 and 1969. These are quite rare, but they did stamp some in this manner.....Cliff

 

Cliff,

Thanks for the input. I've gotten a lot of info from your book too, and I'm not finished yet. I'm anxious to get this entire project on the road and see how it all works together.

Thanks,

Ed
