What would be the correct Quadrajet date code for my Camaro?
« on: February 16, 2018, 08:42:55 PM »
I was sure I had asked this question before, but damned if I could find it in the archives, or any notes I thought I would have taken from it. 

Anyway, my Quadrajet carb on my 69 SS350 is not original and I would someday like to remedy that if I can.  I currently have a 7029223 IY  2488 on the car and a 7040511 QT  0620 I bought at a swap meet many years ago. 

Anyway, I know the number I need, which is 7029202 with the second to last digit possibility of a 0, 1, or 2 for Chevrolet, and the last digit being an even number for automatic.  What I don't know is what would be a good date code?  The date code is a 4 digit number with the last digit being the year (ie:  _ _ _ 9), and the first three digits indicating the number of days into the year.

My body date code is 04C, with my original block date code being  the 2nd week of March.  How do I find out what would be a proper date code for the Quadrajet?  What determined this?  What range of numbers should I look for?  Is there a chart somewhere that I can print out or refer to?  What is the source of this info?

Thanks.

Correct me if I'm wrong, but I believe the carb would have been installed at the assembly plant, Norwood? So date wise, it's not directly correlated to the engine build date. Could be before or after, I think? But obviously before the car's assembly date.

Julian dates for the Rochesters, also appears on parts like the throttle body (top of the flange near the stud hole, rear of the carb). Last 4 digits of 9202 is the correct part # for the 350 L48 auto, my Pace Car included. I have a couple of examples if you need pics -
