For reference a 427 is 7.0L (a liter is just shy of 62 cu inches, just for reference). 6.6 is ~400 inches and a 6.4 is just shy of it...

Lets hope this means that Chevrolet will be producing a MUCH more inexpensive block casting capable of a 4.125" bore than the currect C5R block.
A 4.000" ls2 block would be nice, but a 4.125" ls7 block would be that much better.

Pocket it? That 20gs is going into a twin turbo kit. As for the 6.4L size that's about 396 cubes right? That used to be a very popular size for Gm motors in the day. I could easily see that being the size they end up going with. Either way I plan getting one of these future z06s one day when the money/opportunity presents itself.
That is a GREAT idea!!!! Good thinking King02SS!!!! Wow, imagine that, you would have a better ride as far as ride/comfort and performance goes AND have the NASTY horsepower with the twin turbo that would leave the Viper in the Vette's tire smoke ALL DAY LONG!!!!!! Not knocking the Viper, it's a still a nasty ride!!!!

I'd take the viper over the vette any day of the week, and in any year of the car except '03/'04. I still like the 02 GTS ACR the best. This may be unholy to say on this board, but performance isn't the only factor. Vettes are too common. Flame suit on.

Actually GM should come up with a modern version of the stingray. Competition for the Modena, Viper, Gallardo, GT, and only make say 1000 of them a year or less. I know I'm not the only one who thinks the Corvette is in bad need of a mystique refresher. It certainly seems as though it has lost the title to the Viper.

c.i.d. is not always the disiding factor in how much power you can make you have to look at the engineering of both engines and the after market technology
long story short i beleive you can get better bang for the buck out of a vette...

The funny thing regarding the above mentioned article is the similarity to a conversation I had with a guy 6 months back whom was working for some area of GM's R&D dept. I was telling him about my tube chassis car and how this was the first year for me running a turbo motor, at that point came his info that wasn't to be leaked as I figure it.
His story was very much like the above article points mentioned but the interesting item that drew my attention to what he had to say was GM was looking to produce a limited addition high priced Vette for 2007 model year and only as a Z07 utilizing a 427 LS motor. The car was to be light weight as mentioned above but the kicker he said to me was the car is to be TWIN TURBO CHARGED. The guy said currently GM has a prototype they are working with that is twin turbo charged but with out going any further into details GM was working the bugs out of it? I guess from what he was saying the engineers where having some problems with the setup and FI in different alltitudes or something like that?
He didn't want to go into details but considering what he already said to me my advice to him would be don't go to the bar and drink it could cost ya very nice dream job. LOL

You could probably count it on one hand.
That is the point though, Vipers are rare. They have to be babied. Their have been around 14,000 vipers made since it's intro in '92. That's 14,000 TOTAL. I don't know the Z06 count for 04, but I imagine it's similiar to '03 in which 8,635 were made.
Vette vs. Viper Alright, the 03 Z06 makes 360+rwhp and is right there in 0-60 and 1/4 with a 500hp Viper, some tests show that a stock Z06 ran a 0-60 in 3.9secs and 11.8* 1/4. (current issue of GMHTP). 2003 Viper ran 3.9 to 60 and 11.77 1/4, that's with 100 more horses(Motor Trend). Imagine, if you will a 500hp 2006 Z06, that car will beat the Doo Doo out of a 500hp Viper all day and it looks better.

Unfortunately, A new stock 03/04 viper will eat up a stock 03/04 Z06 in a straight line drag race from 0 to 120mph. That is why i had to put 4.10 gears, full length headers and an air intake on my 03 Z06 (and of course dyno tuned it also), so that i could teach those VIPERS a lesson!!!

Regarding the Viper vs Vette thing:
Not to be an *** or anything, but these discussions just end up going on forever. There's a lot more to these vehicles than what you see on paper, and with the fact that this is all based on opinion, there's no right or wrong answer.
I personally prefer the Viper for its exclusivity and style, but I definitely respect the Corvette for what it is.

GM has created the monster they wanted. Everyone has heard from a good source something different for the 2006 Z06.
A year ago, I heard they were looking at three different engine combo's and they settled on the 6.4L. They can easily make 480hp and meet all the government requirements thru 2010 but were having trouble making the next 20hp. If they only had to meet 2006 requirements, 500 hp was in the bag. Also, we hear there is some type of 500hp ceiling on insurance/government regs for mass produced autos. Finally, the Z06 is going to be a "wide Body" with carbon fiber hood, fenders (front and rear) and possibly the roof. 2800lbs is the goal.
In only 4 months we should know which "source" was correct.

It should also be demanding, in as much as it's a challenge to drive. If you get out of the car, and your NOT shaken, sweaty, and anxious--then you really haven't been for a drive.

J-ROD,
We all know the importance of driver skill when it comes to drag racing manual tranny high performance cars like z06 and Vipers. You are a SEASONED Gear Banger who can drag race with the best of them here and something tells me if a driver of your exact same skills was driving the VIPER, and both cars had equally good traction at the track, the stock 03/04 Z06 vette would see times between 12.0 to 12.3 and the 03/04 Viper would see times between 11.7 and 12.0. These times are based upon professional road tests conducted by various professionals and you know that .3 tenths of a second in a drag race is pretty wide magin.
