What it tells you depends on what side of the engine it is from. Since it is 9 digits long, I'm guessing it is from the driver side of the engine, which makes it the car/engine serial number. This number decodes as follows:
4G4006709
4= Series 4400/LeSabre
G = 1960 model year
4 = built at Kansas City, KS
006709 = sequential number, range for KC was 001001 to 032090
You said you were working on an Invicta, if this was the original numbers matching engine then the engine serial number should start with a 6 and match the serial number plate in the driver door jamb. This engine is from a LeSabre, so you will need to find the engine production code. The engine production code will be found in the same location on the passenger side and it is usually less than 9 digits long. Bill listed two of the engine production codes used in 1960, the complete list is:
L3G = low comp. 364 V8
3G = 364 V8
4G - 401 V8
The format AB123 didn't start until the 1963 model year, so in 1960 the numbers following the engine production code are a sequential number, which can be upto 6 digits long since 1960 Buick production was 253,999. My guess is the engine production code will start with 3G, making it a 364 nailhead V8.
