Thanks Kurt
I do know they are 1966 L79 Nova carburetors.
What I am mainly concerned about is the form of the number stampings and the early date for the 5B1 carburetor. The form of the stampings is quite different. The 5B1 looks like it is hand stamped and there is what looks like an over stamp at the and of the list number like it was the wrong suffix. Although, I have seen pictures of other 3245 carburetors with the same date and they have the same X or star on the end of the list number. I have also seen versions as early as 5A. This seems really early for the 1966 model year. Is this normal?
The 831 looks like it has been machine stamped. I've also seen pictures of other 3245 carburetors with the 831 date. Seems like Holley ran the carburetors in batches on certain dates. Is this normal?
The other thing is that the 5B1 does not have the DC suffix in the GM part number. The other 5A and 5B carburetors I have seen also don't have the DC suffix. Is this normal for assembly line carburetors then?
