Hello,
I've been operating under the assumption that this example was a real car.
DUH!!!
I need to spend less time here and take a class in 'Reading For Comprehension'.

Hello,
I've assumed it was a Rochester carb.
I believe the Quadra Jet carbs were built in Rochester N.Y. at a rate of about 15,000 per day. Yes, 15 thousand.
There were many GM plants that needed carbs every day to assemble cars.
Rochester and St.Louis are about 800 miles apart.
So.... physically possible but likely? Probably not.

This is the answer that makes the most sense to me. A carburetor and a car made on the same day, 800 miles apart, would not likely be acceptable to NCRS. However if the part number of the carb is correct but only the date code is wrong, then NCRS would likely grant partial credit.

Thats how it was explained to me at Texas regionals. Which is fair in my opinion.

I posed this question over on the C1-C2 forum (careful to make this generic and non-MY or component specific) and the answer for restoration purposes, judging etc. is that date coded parts (such as carbs) are generally to be minimum of +1 day to maximum of 6 months prior to production date. There are some specific exceptions to this general rule. 
Thanks all!
Thanks all!

The supply chain and assembly lines were often very fast, and the +1 day rules should be fine for a carb (better some days more).
How you say it depends on which parts are. It must be a realistic time estimate for the respective part.
