Sorry for all the confusion!!!

Actually, the new photos prove it's a 364 nailhead.
4G2010808 (car and engine serial number, always 9 digits)
4 = Series 4400/LeSabre
G = 1960 model year
2 = built at South Gate, CA
010808 = sequential number, range for South Gate was 001001 to 022098
For Buicks, if the car has its original engine then the car serial number (located on the tag in the door jamb) and the engine serial number stamped on the driver side should match for 1957 and later cars (no such thing as "numbers matching" for 1956 and earlier Buicks), so your car has the orginal 364 in it.
3G 93403 (engine production code, 3 to 9 digits depending on code)
3 = 364 nailhead
G = 1960 model year
93403 = engine sequential number
The engine production code is not related to the car or engine serial number. For 1959-1962 the engine production code and the engine serial number look similar, so it can be confusing. 1962 is the hardest year to identify because Buick generally used a 1 that looked like an I when stamping the engine production code and serial number. For 1962 the year code is I, so you have to determine when I means I and when I means 1. For 1963 Buick introduced a new engine production code format so that it could not be confused with the engine serial number.
Thank you for your help and getting me straighten out. Sean!!!!
