Rochester Carb Number Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What are the 4 numbers under the 7 digit carb ID number for and how do you read them. I thought they were a date code but just read an article that says the date code was in the 7 digit carb number. Maybe a day code?

Thanks, Scott
