Ford 221 engine number I.D serial number

[scottly 475]

Hey guys, does any one know how to break down the ford 221 engine serial number? I have a pre crossflow engine that came out of a ford xw falcon 500. It does not start with jg23 like the car serial numbers, the engine starts with A27Z1. Did xw’s have matching engine numbers to the vin? Or is this engine from an American car? 
 

any help would be great there does not seem to be much info around on this stuff.

Can't help you with the number, but 221 was an Australian and argentina only engine, the yanks didn't get them, at a guess the engine could be from a Sydney built car with that number

Thanks mate that’s handy to know. There doesn’t seem to be much information about engine numbers with the 221
