The Ferrari also redlines 1st gear before the vette, and has a rear weight bias, so it will probably be faster off the line. It will also shift more quickly. I think it's a tossup in a straight line.

The problem with that is nobody has seen a true dyno of either of this cars so judging power bands is basically not going to be possible until then.
But looking at the RPM peaks and the respective numbers the Ferrari is going to have a much more peaky powerband compared to the Vette.
Secondly the Vette's gearing IIRC hasn't been announced but even if it's using 3.15 gears(which I doubt considering the last Z06 used 3.46 gears)compared to the 4.30 gears in the Ferrari will not be enough to beat the Z06 off the line. The Vette has it's peak torque lower in the RPM range and like most massive pushrod V8s it won't have a problem with the low RPM torque.
Just look at the numbers. 342 lb/ft at 5200 RPM vs the Vette with 475 @4800 RPM.
The Vette WILL be faster off the line. They are figuring the Z06 to have a 0-60 time in like 3.8 seconds.

I don't know which will be faster around a track, but I'd bet a lot of money that the Ferrari is more fun to drive. I drove a regular C6 recently, and it was very disappointing. I doubt that they'll recapture enough fun in the Z06 model to compete with Ferrari (or even Porsche).
I also saw a review of the F430 which claimed that it's best feature was the new stability/traction control. It is apparently much less intrusive than on other cars while still being safe. So regular drivers can drive it much faster without having to worry too much about killing themselves.

The Z06 C5 and the regular C5 are night and day. We will wait and see of course but the Vette will be as fast or faster I'd wager.
Ok I'll stop hijacking the thread now.
