I'm so glad I haven't bought a Corvette yet. Sounds like the '08s will be worth the wait!

Does it use the actual L92 block?
Does it use the L76 intake?
The hollow stem valves are a nice upgrade over the regular L92 valves.

Does it use the actual L92 block? Probably
Does it use the L76 intake? Doubtful. Bet it's an upgrade over the car/truck intake.
The hollow stem valves are a nice upgrade over the regular L92 valves. Absolutely.

If you read further on in the spec charts, 2.56's are standard with the A6, with the 2.73's being optional. All M6's have 3.42's.

Do the math:

C6 with 2.73 ratio = 11.00 starting ratio (4.03 1st gear x 2.73 rear)

C6 with 2.56 ratio = 10.32 starting ratio (4.03 1st gear x 2.56 rear)

F-body with 3.23 gear = 9.88 starting ratio (3.06 1st gear x 3.23 rear)

F-body with 3.73 gear = 11.41 starting ratio (3.06 1st gear x 3.73 rear)

So in a nutshell, even the stock 2.56 gears in the C6 give you more starting ratio than the optional 3.23 gears in the F-body. You would need a 3.73 gear to have a more aggressive starting ratio in an F-body.
