Zo6's where starting to deliver about two weeks ago. It's being dyno'd at 445-450 rwhp stock. That's stock. Wouldn't that make it about 530 hp. Chevy must've underrated these cars as well considering they're listed as 505 hp on the side emblem.

 

I have to admit that 2006 Z06 Vett is sweet, but for a starting price of $65,800.00 not for me. I could have purchased 2.7 Mustang GTs for that, or at least what I paid. That is a whole different class of car though......

 

Sorry about the misconception guys. I got a ZO6 but it is a 2004. I paid $36000 for it. It was my daughters car. It had 20K on it. It is rated at 405(underated) Actually has about 430 to 450. Has a power to weight ratio of 7.7lb/hp.( Remember the Shelby will weigh in around 3880#) It does a 12.4 1/4 and hits 60 in 3.9. (check out google) put in Corvette ZO6 2002. They tested the 2002 more since it was their 1st model with the LS6 in it. It has the 5.7 liter in it. New Z's have a LS7 and are 7 liters. They didn't make one in 2005. I got a lot of car for the money I paid. Reason was I didn't want to run thru the hassle with Ford and go into a bidding war with other guys. Got a F-150 though and it is a great truck(made in Canada)
