I found this in the Corvette Forum.
Compared the numbers to at least three different postings on similar subjects. Thought you would like to know.
C6 Z51 6500 RPM
1st = 50 MPH
2nd = 73 MPH
3rd = 105 MPH
4th = 151 MPH
5th = 213 MPH
6th = 265 MPH
It was also mentioned that the LS2 cam stops making power at around 5600 RPMs.
