LS9 DOHC / LS8 / And end of life for LS7 Thanks to our friends at digitalcorvettes, more info on these awsome offerings from GM have come to life.
Looks like 2011 is the switch from LS7 to LS8 for the Z06.:thumbsup:

I was a bit surprised to see this the other day, thought you would enjoy seeing it as well.
Is this the first mention of DOHC for the LS9?
EDIT: Look in <upper right corner> of document for "DOHC" and <center> for LS9 reference.

In case the information has been tainted with trackable "disinformation" I will summarize but must be vague. I do not rule this out as being an intentional leak.
- The "Corvette SS" undeniably a go.
- We are at the very beginning of the program.
- Will be limited #s
- Not indicated to be "blue devil".
- Will be outfitted with a "charged" LS9.
- This will be a Corvette-only motor not to be in a caddy.
- The LS9 is a smaller displacement motor than the LS7. <----
- The "Corvette SS" will be top dog, Z06 will not be.
- Well over 600 HP.
- No test/beta/pilot Corvette SS exists in any shape or form. So don't waste your time looking for one yet.
- Unlike info on some other sites, this Corvette WILL NOT be seen for a very very long time.
I think there are others that know this info, but there are a lot of shaking knees when it comes to even discussing it.
To our GM viewing audience, just want to say thanks for keeping the Corvette line exciting and for continuing to take the car to new levels. Great job. Keep up the good work, we love it.

Look at the date of the thread; 10-20-05. Seems like this guy is "in the know" pretty good with someone at GM. Just from a business standpoint, it doesn't make sense for GM to simply discontinue the LS7 after spending so much on R&D, tooling and production costs. My guess is it will show up in other GM performance vehicles (no dry sump) to recoup some of the high costs of the engine. In fact it's probably a given it will, especially if they drop it from the Corvette line.

I don't see what is wrong with twin screw superchargers. They have low end boost of a roots style and can almost match the high end boost of a centrifugal.
I personally hope that they use the new Rotrex superchargers that are just becoming available in the U.S. Those are cool.
