The carburetor for 69 Corvette with 350/350 hp was the Rochester Quadrajet, GM part number 7029207. Intake manifold was cast iron, casting number 3927184.

Every now and then, there is a question that brings it all together for you. This was such a question for me. My first impulse was to post you back asking which transmission your car had, since the engines generally have different carburetors depending on whether the transmission is automatic or four speed. But I resisted the impulse and checked the spec book, and it only gave one carburetor number: 350/350 with four speed...nothing for 350/350 THM.

After double-checking another reference, I discovered something I had never realized before: Ladies and Gentlemen, from 68-70, the 350 hp engines were NEVER equipped with automatic transmissions. I hope I continue to learn something every day. :D

Chuck, I noticed the same thing answering the same question only a couple of weeks ago. My contribution to this thread is the following link which I find very useful for identifying carb #s. :) MJ

Yuk, Yuk...Thanks, but no thanks. I have a hold on one tar baby...I will consider other projects when I get this one finished. :D :D

Okay, so you nailed the carb question. How about a really hard question?

How many yellow Corvettes were produced in 1973? I'm not asking because I know ('cause I don't) but because I want to know! Every resource I've checked says no stats kept of colours for 1973 and I just find that hard to believe!

There's a reason I call her the Nuclear Banana!!

Uhh, does that mean you can't answer the question or is it a ploy for time? :D :confused: :rolleyes:

I was attempting to say in a humorous way, "I haven't the foggiest, and there ain't no way to find out the answer" (I only know what I read in books). :D

Yes, Mac, the best minds in the Corvette hobby have already concluded that if records were kept, they are now destroyed. You are probably right, there must have been paint color records kept at one time; for marketing if for no other reason. Shoot, thousands of us would like to get a copy of our car's original order sheet or tank sticker, but the "minds" have concluded those were also destroyed. Every now and then, a rumor starts that a search in an old warehouse might reveal these lost records, but I don't think its going to happen...there's a better chance at finding the Holy Grail.

Holy Grail? Oh, heck- I got one of those. It's a great gag, watching your buddy pour beer down his shirt instead of down his throat!! :cheers:

Hey, I was hoping someone was having more luck than me- my research has been "unfruitful!" :lol: :lol:

Chuck is a great source of info. The 350hp cars didn't come with an automatic option as the camshaft specs really wouldn't work well with a stock automatic. Road tests, such as the Superfast80 supplied R&T article on the '68 350hp engine for example, basically found it lazy below 2500-3000rpm. This is with the mandatory 4 speed. Aftermarket cams with similar spec's are recommended only with manual trans or high stall converter automatics.
I have this bad habit of spending too much time on the forum at work.....

I've got the Crane series Blueprint 350/350 cam in my automatic 3.08 rearend car, and it is a real dog below 2500 rpm. But from 2500 to 5500 it pulls like a demon. Previous owner put the cam in, I'm getting ready to pull it out and replace it with a more modern cam.

Smokehouse69...you might want to try a Comp Cams XE256 or similar from another manufacturer to give you the pull off the line. Your cam would be real, real nice in a stick with some higher gears!

I'm going with the XE262, I know it doesn't perform as well at lower RPM's as the XE256, but I've got a 3.70 ring and pinion that I'm just trying to get enough nerve to install. I figure the XE262 can't be any worse than the 350/350 that's already in there.

FYI . The 7029207 is still available from the general. I don't recall the parts latest #. It does however still have the 7029207 stamped in the usual location. Obviously the date code would give it away from an original 69

I have the same gears as you, and have tried a few cams. I had an old Speed Pro 186R that would pull like crazy even up to 7000 RPM :eek: . But talk about crappy idle! I settled on a Crane Powermax 288-H which is not as radical as the number makes it sound. It has a wider lobe seperation and is dual profile, so it idles pretty much like a stocker. I am sure you will be able to find one you like. Funny Chevy dictated a manual trans with that motor, yet the M-21 has a 2.20 first gear. Anyway, to get to the original part of this thread, yes, the General still sells the 69 carb new....but it costs a lot of money! If I remember right it's around 500 bucks.

Default Getting back to the carb question

All,

I want to dig a bit more into the carb question:

My 69 350/350 has a '72 carb on it. Not the end of the world, but since I am doing a frame-off, then I want to take the time to find the right carb.

According to http://www.chevyhardcore.com/tech-st...ication-guide/ the following info makes sense to me:

7029207 - That means:

70 - Indicates that it is the carb built between 1966 - 1975
2 - Indicates Built 1966 - 1969
9 - 1969 model year
2 - four barrel Q-Jet
0 - Chevrolet
7 - Manual

Now, what it ALSO says is that for the last digit, any odd number (1, 3, 5, 7, 9) would indicate manual transmission.

MY QUESTION: Does that mean that the "correct" carb could ALSO be:
7029201
7029203
7029205
7029209

???

I see listings for the 1, 3 and 5 on ebay, but they don't seem to indicate that they were pulled from a vette.

So: was the 7029207 the ONLY carb for a 69 350/350 manual... or are the other options (1, 3, 5) correct as well?

Thanks,

v.

(ps: if someone has a 7029207 with a date code that is before "3058", PM me... it's hard to find a carb for a 1969 that was built in November of 1968)
