C3 Quadrajet Carb.

[Art Ives]

Can anyone identify this carb I bought for my 1969 427/390 4spd? In reading my restoration books I suspect it may be incorrect for judging. The number on the side is 29715 FH 3548. Thanks, Art Ives

Re: C3 Quadrajet Carb.

i can not find a 29715 anyplace but your S/T 69 427/390 HP corvette takes a 7029215 and you may have misread the number

PS

7029215 was also used on several different 396 engines in chevy cars

Re: C3 Quadrajet Carb.

Art, according to what I can find, the 3rd digit can only be a 2 or a 5. 2 is 49 state carb while a 5 is a Calif/High Altitude carb. Are you sure it's not a 2 that looks like a 7?

Re: C3 Quadrajet Carb.

It looks like I have a typo. On the side of the carb it has 29215EH 3548. At the time I bought it the carb rebuilder told me that they didn't always put the 70 in front of the number. Me new at restorations, I have a tendency to trust vendors. Thanks Art

Re: C3 Quadrajet Carb.

I have an original carb on myn 69 390 that doesn't have the 170 digits.

Re: C3 Quadrajet Carb.

Larry, What numbers are on the side of your carb? Maybe I was told the truth. Bought this carb at the Texas Motor Speedway. Just an old car show. Where is yours dated at? I can't find that either? Thanks, Art

Re: C3 Quadrajet Carb.

a 1969 carb would only have "70", "170" did not start till 1976.

date of mfg

3548 means it was made the 354 day of 1968

Re: date of mfg

Thanks Clem, I guess this puts me out of range on my car. My engine date is 6/27/69 or did I make it by one day? Art

Re: C3 Quadrajet Carb.

Clem I just re-figured and I think that means that the carb build date is Dec 20,1968. If that is the case I'm 7 days out of the 6 months. Is that not good for judging or is there a little leeway? Art

Re: C3 Quadrajet Carb.

art, i know nothing about this judging stuff but i am sure some one else will pop in about this.

Re: C3 Quadrajet Carb.

My carb is 29201. Date is 3568. Yes I know that it is not correct but I do belive it is the original carb on my car. The Rochester data shows it as a corvette carb along with 385hp Chevrolets.

Re: C3 Quadrajet Carb.

Thanks Larry for your help. Our Carbs were manufactured within 2 days of each other. My carb is strictly used with the 4 spd as best I can figure out. I think yours was for automatic but again don't quote me. Thanks again. Art Ives

Re: C3 Quadrajet Carb.

Pretty interesting.. the 201 IS a four speed carb though. I have the Rochester application list and specs I got from Lars Grimsrud. The two carbs are almost identical. My car is an October 69 car so my carb is a too early also. I do have reason to think it came on my car or was replaced very early in the cars life though. Lars said he had seen 201's on 69 Corvettes before that he knew were original. My car was fairly unmolested when I got it and mostly original and it just looked like everything had aged togeher. It is kind of a feel you get after owning Corvettes all of you life. Anyway the numbering method is consistant with yours.
