C6 engine background
Although I cannot be sure, it seems that the XV8 concept
engine will see the engine bay of the C6. It may be of interest
for some of you to follow several patents granted to General
Motors recently. The first is entitled "Valvetrain for a pushrod
engine," by Alan W. Hayman. It is U.S. Patent number 5,560,329.

You'll notice his comments at the end of this article:

As you look at this patent, notice that there is
another patent that references Alan Hayman:
patent number 5,934,232. Don't be surprised if
you can't determine the full details of the engine.
The goal of these patents is not to lay out the
specifics of an optimized production design -
just to pee on the fire hydrant well enough
to ensure exclusivity.

Re: C6 engine background (Runge_Kutta)
While I have little doubt that the technology in the XV8 will ultimately make it to Corvette, I don't think the current small-displacement narrow-angle design will.
Barring some magical 1,000-lb mass reduction, future Corvettes will require more power, not less. We can assume that the 4.3L displacement and 300hp output are maximums for the XV8's present architecture.
It seems clear that XV8 is intended for midsize and large sedans which presently house 3800 Series II V6s.
Also, Corvette buyers are too conservative to embrace such an advanced package. I bet with C6 we see two in-block cams in an otherwise-familiar LS1-type 6-litre-range 90-degree V8; the rest will first be proved on technology-insensitive trucks and sedans.

Re: C6 engine background (Runge_Kutta)
Sorry about that!! What I meant was that the ideas incorporated
into the XV8 will see their way into C6 - not that the exact engine
will go into C6. I believe that XV8 is the technology demonstrator
for the GenIV small-block that's going to go into many GM vehicles.
The million dollar question is where is the XV12 destined to go????
The answer would seem to be Cadillacs but maybe this $100K Corvette
that Bob Lutz was toying with will get it???

Re: C6 engine background (Runge_Kutta)
I see the XV12 going into the next-generation Seville first (only because the DeVille's move to the Sigma platform was deferred). Maybe it'll make it to a FWD DeVille, maybe not, depends on packaging I think. Then it'll replace the supercharged Northstar V8 in the XLR (once the top Corvette has the ability to exceed its performance). It ought to go in the Escalade but I doubt they'll cross this car motor to the truck kingdom, even for Caddy.
I would argue that CTS needs a V8 a lot more desperately than any Cadillac needs a V12. Though I'd love to have a V12 DeVille...
