The AD engine blocks were not sold in any given year or model but over the counter as build/rebuild parts. There's really no telling when your engine was built or what the configuration is.
The engine is a 1600 cc manufactured between late 1970 and early 1973.
That's a twin port 1600 from between August 1970 and July 1973.
This is a 1970 through 1973 1600 cc engine, the "AD" and the 6 digits after that are considered the engine numbers.
Looks like somewhere between Aug 1971 to June 1972. See the link below: http://www.lennysvw.com/type1chassis.htm

No, 1915 is a number. It represents a year in the Gregorian calendar. It is not a noun.
1968.
There is no designated last year for the AD calendar. AD takes it year by year and keeps going that way. It is not like the Mayan Calendar. So there is no designated last year in the AD calendar. Nobody knows. It could be this year. AD will just keep on going until the end.
