Holley 6210
The Holley 6210 is a spreadbore replacement for a Rochester Quadrajet, and was not an OEM carb. It never was original equipment for any car. As for the date, I think the first digit is the year---zero could be 1970, 1980, 1990, etc. The 354 should be the 354th day of the year.

GM never used it from the factory, so it's most likely that someone has installed it to be able to use a spreadbore manifold on the engine, or to replace a Quadrajet.
There is some additional info on these carbs and their more common use in this thread...

Holley 6210
A spreadbore carburetor will not fit on an intake manifold made for a squarebore Holley carb. Besides having the wrong carb, you will also have an intake from a passenger car or an adapter on your original manifold.
