First, welcome to the group. It's nice to have someone from Puerto Rico join up!
Second, regarding your question, the Z10 was a Pace Car replica, but in a Coupe configuration instead of the normal Convertible. It included (among other things) the SS package and the Rally Sport package, but it wasn't available with the Z28. The car you show above shows Z28 emblems so it's not an SS, and it doesn't have the Rally Sport option, so it isn't a Z10 unless the Z28 emblems have been added and the Rally Sport components removed. Did you get a picture of the trim tag on the firewall? Or the VIN? These will give us more info.
And you can read more about the Z10 package
