2008 engine upgrade
There will be two levels of Z06, 505 HP, and 650HP
When I asked him about base he said there was no engine upgrade, now I know he may not know for sure but this guy was extremely knowledgeable about everything else. It makes sense to me, my impression of the factory is that quality and reliability is extremely important, if not #1. They want the Vette, and all GM cars to loose the notion that they are inferior to Japanese & European cars in that regard. Ultimately they want to make money. It would make sense for GM to boost the Z06 to keep it the performance king and concentrate on reliability and quality for base. Sure they will upgrade base over time, but it doesn’t need to be the performance king, that is Z06’s job.

Lose, not loose.
The Best of Corvette for Corvette Enthusiasts
he offered the information on Z06 engine while giving the factory tour, I then specifically asked him about base, maybe he just hasn't heard anything about it.
like others have said, we'll know for sure in April

Yes, IMO GM wants to re-take the hp crown from Dodge which just released it's re-worked 600 hp/576 ft-lb tq Viper. Although Corvette will have to do it with a SC'd engine versus the naturally-aspirated Viper, Corvette will likely catch-up to and surpass the Viper in rated hp.
I don't know if there's any extra emphasis on "reliability and quality" for the base model because this is something GM does in due-course anyway. My 2005 C6 has been extremely reliable and trouble-free but that's not to say there isn't room for improvement.
The rumor is there will be a minor increase in hp with the new engine in the 2008 C6. This small hp increase will purportedly come with the new Displacement on Demand engine (which IMO should not be in a high performance Corvette).










Except the intent of DOD is improvement in fuel economy. Shutting off cylinders won't increase HP. It WOULD allow you to increase HP in some other way and then get back to better MPG while cruising. In any case, it doesn't belong in a performance car. GM tried it in the 80s and it was a total failure. They THINK they can make it work this time by better computer control of the engine. Blipping the throttle and such to match torque when changing cylinders. But how much can you gain? It takes a fixed amount of energy to move the air out of the way at speed. That translates into a fixed minimum amount of fuel. So now the question is, do you burn all that fuel in 4 cylinders or 8? If you are burning it efficiently to begin with it's hard to believe you can get more than a couple percent improvement in efficiency by burning it in 1 mass rather than 2. And the throttle blipping in stop and go traffic can't possibly be worth it. I must be missing something.

DOD has been around for a few years now and is operating w/out incident. If you had actually driven a car w/ DOD, you would know that it doesnt engage in stop and go traffic. I've said it before, but for the sake of those who haven't been present for the other DOD threads, it only comes on in cruise, and VERY light throttle conditions, or when slowing down from speed. If you're going more than about 65-70, it won't be on at all. If you're in stop and go traffic, it doesn't come on. In my real world experience with it, it mostly comes on when I'm slowing down from highway speed (on the brakes), or when coasting down a hill w/ my foot off the gas. It's just not as intrusive as some of you make it out to be. And if you don't like it, edit it out w/ a programmer or laptop. It's really that simple.
That said, I'm not sure the Corvette will have it.

The Z06 will, eventually, be offered in the "Blue Devil," "Sting Ray," or whatever else they are calling it this week, format w/ a s/c engine making north of 650 h.p. It will cost 6 figures, count on that. You can get that kind of performance right now out of the LS2 with s/c, and it won't cost 6 figures to do it.
The "base" C6 is supposed to get the new LS3, with a massive 2-5 h.p. gain! IMO, why fix the LS2 when it ain't broke? We all know that GM, in screwing around with a new powerplant, will simply have "issue" for a few years while they work it all out. By then, the C7 will be available, which would be a perfect time to rethink things (and, hopefully, give them time to properly test an engine replacement).
Happy Vette-ing, All!
The small increase in HP may come at the expense of future modding.
