Well, a few people have mentioned this. The 2008 C6 will use the
Tremec TR-6060 M6 transmission rather than the T56. here's the Tremec
light-duty manual transmission line up;
* Light-duty transmissions
** Tremec T-5 transmission
** Tremec T-45 transmission
** Tremec TK0 transmission
** Tremec TR-3550 transmission
** Tremec T-56 transmission
** Tremec TR-3450 transmission
** Tremec TR-3650 transmission
** Tremec TR-4050 transmission
** Tremec TR-6060 transmission

I see a 650 lbs*ft torque rating.
======================================== =====
Then there is the LS3:
OK, let's look at the two different 3V head designs that use
a single internal camshaft. I am reasonably sure that the LS3
will use a variation of what is shown in patent 6505589 but
I wonder what the valvetrain will look like. From Figs. 1
and 2 in 6505589, you can see that the head is designed
for direct injection from the top of the combustion chamber.
Patent 6505591 details an intricate way to simultaneously
actuate the exhaust valves while maintaining space for
the DI at the top of the combustion chamber. Patent
6668546, Fig. 5, shows the combustion chamber of both
the single and dual internal camshaft designs from a
ways back.

http://www.freepatentsonline.com/6668546.pdf (Look at Figure 5)
Here's the new valvetrain. As you can see, there is no longer
any place to put the central injection DI injectors.

This could mean many things. First, that no 3V head will
get central injection. It could also mean that there will
be a DI version and a non DI version of the heads. Lastly,
GM could have decided to abandon low pressure, air assisted
DI for high pressure side injection.
Someone needs to spill the beans here ...

Is that standard Vette/CTS, or super vette/CTS-V? 650 lbs of torque transmission... makes me think high end models only.

So it could be the supervette, and maybe to the cts-v or sts-v (heavier and would need something stronger)
It also showed the GT500.

Re: From our friends at the Corvette Forum...2008 Corvette powertrain info
Had a Viper in there too. I would think the 6060 would be overkill for the base engine, but I've read from several sources over there that the LS3 is a done deal for MY08, and it's packing 435hp. Makes sense, Vette gets it in '08, Camaro in '09? Hells yeah!
It didn't specify which model, but it did specifically say 2008 Corvette, and 2009 Cadillac. If the supervette assumption is true, then that would mean it was an '08 model for sure (I had thought it would be an 09). Of course, it could just be going in the Z06. Then again, it could be going in all of them! I think its a safe bet that the CTSv will debut a year after the new CTS, given this information.

Re: From our friends at the Corvette Forum...2008 Corvette powertrain info
I am interested in the 3v head and direct injection. Combine that with VVT, and are pushrods that "outdated"?
How sure are we going to see a 3V head on the LS3?
Will there be different variations of the 6.2 V8, one with 2v heads, one with 3v?
There seems to be a lot of work being done in GM Powertrain.

0-60 in 2.5 seconds?
Wow, erm...
I gotta chalk that one up to a serious case of optimism, only because that number is basically incomprehensible.

Re: From our friends at the Corvette Forum...2008 Corvette powertrain info
I'll just say what I heard as a rumor:
From what I've seen or heard, they're aiming for 0-60 in less than 2.5 seconds. And they've beat it, by a bit.
They're aiming for over 200 MPH. And they've done it. (Well, duh.. the Z06 goes like 197 doesn't it?)
Something special happens around 140 MPH and around 190 MPH
It'll cost around a hundred grand in US dollars (which was pretty much already known)
They want to beat the best in the world for less than a quarter of a cost. And, from how it sounds, they will.
And that's all I've got to say about that

I guess I'll believe it when I see it (the super vette stuff that is, not the LS3 stuff), the reliability of that info seems very iffy at best. I'll be pretty excited if it even approaches those numbers...

2.5 to 60 mph?
Eh.
Dodge's Hennessey SRT-10 Viper Venom 1000 does it, as does the forementioned 2006 Bugatti 16/4 Veyron. The 2004 Chrysler ME Four-Twelve Concept did it in under 3 seconds. I was at Laguna Seca when Chrysler was running the car for the press (didn't get in though... elite press only
). Finally, unless I'm mistaken, that's about what the ZL1 Camaro concept ran the 0-60 run in. So it's not new territory.
However.........
that's really &^%$#@%! quick!
