I don't think they will bump it to 450. I think that might upset 05-07 C6 owners, and I think they know that. It wouldn't suprise me at all if the C7 had 450 or even more. But that's a complete car redesign. An extra 50 hp would make a big difference.......especially 0-100, and I just don't think they will do it. My guess is 425.............maybe 435. But now that I think about it, GM has in the past done things that absolutely blow my mind.........so you never know.
Hell, the way some of you think, we would still be driving a Corvette with a Blue Flame six - 0-60 in about 12 seconds and getting 11 mpg.
We are in a horsepower war not seen since the late 60s. GM simply is responding, and I'm glad they are.

Just imagine what we'd be posting if they weren't trying to keep up with the competition~!!! And they kept the "base" horsepower at 345 or so.
Right now, there are base V6s at 300+ hp. Torque lower, of course.
but, just imagine....I doubt if anyone would be sanguine on CF-C6.

I have watched some of the information on the web for this, and I believe the engine will have 450 HP if GM includes direct fuel injection with this engine.
The L92 6.2 L in the Escalade produces 403 HP. Its rated rpm is 6000. With the "LS2" features added, and higher rpm capability, this engine should easily reach 425 HP. Note that the L92 already has VVT.
Since GM's most profitable product lines are pickups and SUV's, I believe they are looking to add all the best features to their V8's so to make these vehicles not only powerful, but fuel efficient. This would include VVT, DOD (or Active Fuel Management, AFM), and Direct Fuel Injection. I would also believe that GM may eliminate a few engines, such as the 4.8 L V8 and the 6.0 L V8, and have just 2 options, the 5.3 L and the 6.2 L. This reduces their manufacturing costs, something GM needs to be concerned with in the current market. For small engined pickups, I believe that GM may utilize their high feature 3.6 L engine (~ 275 HP).
I have been following the Yukon/Tahoe hybrid news, and I noticed the following info regarding its engine (see link). It will have DOD, VVT, and a 12:1 compression ratio. This high compression ratio suggests direct fuel injection to me. Therefore, I believe that this new LS3 in the Corvette will likely have 450 HP!

There are several other reasons to anticipate direct fuel injection, and one reason is that it helps to lower emissions. GM has direct fuel injection on the Solistice GXP, and has announced that the high feature 3.6 L V6 will have it in the near future. Also, GM will look to provide more engine power to its customers, but also will look to increase fuel economy. This is the responible approach for a large company that sells large "fuel thirsty" vehicles, because they always seem to come under the microscope, even though their pickups and SUV's get better mileage than their competitors like the Toymota Land Cruiser.
Finally, in the American Lemans Series last year, the Corvette team just narrowly defeated the Aston Martin team for the championship. Direct fuel injection could be applied to the C6R, providing more power to help the team complete with the currently more powerful Aston Martins.
I'll agree with the 450 HP, and would expect the LS7 to go to something close to 550 HP.

I wish I grew up when you did, I'm still stunned when I sit and think that you could have walked into a dealer, and for $4,000, ordered a 1967 big block convertible with a stinger hood, 427 cubic inch engine, HD brakes, etc. Or done similar for a Camaro SS/RS, Chevelle, GTO, Challenger, or Charger! But -- given the great cars out today: C6, Dodge Charger, Magnum, Mustang, and upcoming Camaro and Challengers, we don't live in too bad an era! Although, it would be nice to be paying $2,800 for these cars, rather than $42K.

The irony is that at $42K, today's cars are MORE affordable than yesteryear, because any idiot with no job and bad credit can get a car loan now!

Acronym for Displacement On Demand. GM's cylinder deactivation technology. I think it's been renamed on everything now to Active Fuel Management...AFM. We have it on our Impala SS LS4 (303hp), the transition is seamless, and so far, NO ONE has been able to tell when it switches when riding or driving the car. The stock exhaust sounds the same under all conditions, though I don't know how they accomplished that. I also don't know how it would sound w/ an aftermarket exhaust, but I have faith that GM would not do this to the Corvette unless it was acceptable to the owners. Does anyone think they will really let it sound like a riced out Cobalt? I doubt it. And if it does, there is already an edit to take it out....case closed.

You and I seem to agree on everything - up until now. Talk to someone who owns a Chrysler 300 C. I'll bet most of them don't even know their car has DOD. I've talked to people who own them, and they say it is totally seemless, and you don't even know when the cylinders are deactivated. I've also talked to a friend of mine with a 2007 Tahoe with DOD (and I"ve ridden in it). Same thing - you can't even tell it has it.
I'll gladly take DOD to get more horsepower.

The only question in my mind is whether GMs version of cylinder deactivation is as good as this.......if it is then no worries. I know it's in an SUV but the engine in my Jeep is a screamer that never misses a beat. They should put it in the Crossfire!!!!!!!! Now that would be a little beast. Then there is the Grand Cherokee SRT8 at something like 425 hp.

Look for 3.42s as the sole ratio on the manuals with 2.56s standard and 2.73s optional on the automatic, at best.

However you may be 100% correct in your assessment but I'd have stay on the sidelines until it was proven technology in a vette. I'll keep and open mind but not with 50+ grand for awhile.

Just remember, cthusker: the vast, vast majority of even Corvette owners, don't mod, don't change a thing. As a matter of fact, the vast majority don't even shift!
That means even if you can hear the difference, either the majority of owners won't, or they won't care. Especially if A) there's more power and B) there's more mpg.
Those are the facts of even) Corvette life. You can dispute it, but they're still facts.

Craig,
The hand held tuners for the trucks already have the capability of turning off DoD. I've also read here that GM may set it up so that DoD is deactivated in competition mode.
My stance is that I'd rather not have the additional complexity, but if it allows GM to put a "bigger" motor in, then I'm for it.
