Help ID a block...

Ok...I already know it's a Mexican...that much I figured out.

The first digit in the casting should be a letter denoting the decade...then the second digit is a number denoting the year..then next denotes the vehicle it came from.

Here's what I have:

75-ZY-6015-AA

So...I know it's from a Mustang because of the Z...but the first digit is a "7"...and the second is a "5".

I'm not aware of a 65 Mexican block...nor a 75. thought they went from 68-74.

Any help??

Seen that site when I was doing a search. Not telling me much besided the year though.. The block is at the machine shop being cleaned and checked right now. Thinking about using it for my 331 stroker. But want to make sure about it before spending another $450 in machining.
