future Ls Generation 5 small block V8
I've heard (Chevy High Performance, I think) that it's going to be a 5.5 liter with DI, VVT, and Cylinder deactivation. Basically it's supposed to use all the new technology they've accumulated over the years into one package. If rumors are true, that's going to be a nasty little motor.
EDIT: I've also heard they may go with a cam-in-cam setup this time for the VVT system.

The 5.5L is a racing-only engine for the Corvette LeMans team. The Gen V small-block family will have 2 different engines - a 5.3L and a 6.2L. The 5.3L will go into trucks/SUVs, and the 6.2L will go into performance cars and possibly top-model trucks/SUVs. The Gen V will have direct injection. I would assume AFM would be included as well. There's a lot of talk about VVT also.
Interesting, I knew about the 5.5 being a LeMans engine, but I thought another racing adaptation was going to happen with it and bring it to production, similar to the LS7 coming from the C5R 7.0.

No interest on the future? I wish we would get more information .From the very few comments this post has had, there must not be a hole lot info out there or there is no interest.
not v8 related but concerning new engine for the 2012 v6 camaro: http://www.autoblog.com/2011/05/17/h...re-horsepower/
VVT is KEY to the new engines. Although i have no proof of what GM is up to as I spent a fair bit of time searching that out and come up with only rumors but... When you look at the performance and fuel economy capable with independantly variable valve timing as in the new Ford Coyote 5.0L its a given not a guess that GM too will be bringing this to the table in a big way.
Cam in cam now you say? Hmmm well.. the one thing I love about GM is they cant risk not having tough and powerful engines in their trucks if they want to keep selling so Im sure it will be as simple as they can make it, while making as much power as possible.
Im pretty damn excited about it personally.
A few downsides though... What the heck is aftermarket cam in cam set ups going to cost? This **** could get pricey and make boost seem much more affordable. Considering the strength of current gen 4 bottom ends and ease of tuning boost safely I bet you'll see more boosted gen 5 builds then NA.
I love me that NA stuff though so we'll have to work on getting the most out of whatever they give us I suppose. Meh I'll be happy when I get this 6.2L VVT build done

well keeps the heat in the engine as well!
)Seriously if I had a dime for every two stroke piston I've burnt ayyayyayyy.
So back on point I am watching what they use for metals and alloys and how they are constructed etc. I figure its only a matter of time before we see a multi alloy lamination type casting or forging process in cyl heads and pistons etc. All with heat control as the main goal. You want as much heat reflection as you can get while minimizing heat absorption and reducing friction etc. Coatings and whatnot are pretty common place nowadays but this is really just the beginning of where this tech will go.
Neat stuff if I only I had ten more lifetimes to live maybe Id have time to research this further and design some of it LOL
incorporating the exhaust manifold into the head is gonna be better than stock manifolds, but now a longtube header is out of the question becauase the have cast the collector into the head. They need to keep their designs aftermarket friendly, or upgrade friendly.
Good idea if the car is gonna stay stock, bad for performance exhaust upgrade.
Just my .02

Man I was about to say adding a set of twins would be so easy with the new V6 design. Im sure we will be seeing more V6 camaro's going alittle bit faster. My poor ls1 stock only makes 25 more then that engine so it wouldnt take much to get that V6 spanking ls1 cars
