Theres no way anyone can identify that as a z06. What from that pic can tell you there is a z06 motor under the hood. So many people have a c6 and just throw on the z06 body pieces for the looks. It a very common thing. People in my dads corvette club do it all the time. Also, many of the kits out there for the c6 run very low boost so it can be legal. They only push 4-5lbs. Only a few kits run high boost and remain street legal.
