The first five characters after AR is the engine type number. Engine type 00530 is a 1300cc engine fitted to, among others, the Giulia GT Junior.
A way to tell the basic engine size without having to remember engine type numbers or cylinder head symbols, is to look at the distance between the top of the waterpump and the bottom of the cylinder head. On a 1300, the bottom of the head is in line with the top of the waterpump. On a 1600 engine, the bottom of the head is 25mm above the waterpump and for the 1750 & 2000 engines, the distance is 40mm.
