Did Carter carburetors come as OEM in my '69?
Was Carter original equipment in '69? My '69 convertible has a Carter Quadrajet. It looks like the serial number is 7029202. It also has L8 and DH under what I think is the serial number.

Kalway is correct. According to the great book (Lars' qjet tuning paper) Rochester had Carter manufacture some quadrajet carbs. According to the numbers you listed you have a quadrajet from 1969 that is set up for an automatic that is not from california.

My late-built '69 350/300hp car has the same carb on it - 7029202 and something cast in the side saying it was built by Carter for GM.
The confusing thing for me is this is on my factory 4-speed car, and I thought they were supposed to have the -203 carb. It this possible, or was it most likely replaced at some point?

GM wasnt very picky when it came to Auto and STD as far as Qjets went
My Qjet is certainly the original and its for an automatic..my car came through with a 4 speed
Unfortunately I cant get the Qjet to run correctly so I have installed a Holley Street Avenger 670.

So your car came from the factory without matching numbers!

I have a theory. The 203 (odd number) was for manual trans cars and the 202 (even number) was for automatics. Both carb numbers were used for a variety of Chevys in 1969, including Camaros, Chevy IIs, and Chevelles. (For the 1968 model year corvettes had unique carb numbers that were only used on vettes. For that reason they tend to be rare and expensive. )
If you look at all those models of vehicles you will realize that there were tons more produced with automatic transmissions than manuals, so the 202 carb would be much more common than the 203 carb. I think it is more likely a replacement, and more readily available (and cheaper) carb.
(Bob Onit, I am not disputing that your carb is original to your car. I am just saying most people finding a 202 carb on a 4 spd it will be a relplacement for that reason)
Checking the TIMJG, The DH code means it was for a base engine auto, and L8 is a date code (month, year) which would be December 1968. Cajun, is that consistent with your car's build date... 1st quarter of 69 or so?
