I like the black roof, black lights, and the fat back tires.  
The thread below goes on and on.  If the 500 hp rumor is true then I expect the car will have a 7.0l.  427ci*405hp/346ci=499hp
Certainly GM can get to 500 hp with a 6.4l if they wanted to try that hard.  There is a guy on ls1tech that is firm about the new z06 being a 6.4l as he is involved in some part of the production process.

In person the c6 looks more compact.  I like the one I saw better than the photographs of them.  So I am more excited about the c6 z06 than in previous days.
Enjoy
