Dont know how valid this info is but I thought I would share this. Don't think this has been posted.
"LS8…
This is another 6.2-liter, smallblock V8 with a supercharger. It also features an intercooler integrated into the intake manifold. This will be the motor going into the top-end Zeta platform cars. The most premium Camaro, probably called Z28, will get this motor.
That said, original plans had this motor going into a Denali SUV or truck, however, those plans now seem to be canceled. Again, this maybe a result of CAFE.
Some of Holden’s vehicles may also get this motor eventually. Initial specs have this motor at 475 to 500 horsepower with a choice of manual or automatic transmissions.
When the LS7 dies, the Z06 will get this motor. Possibly, slightly uptuned from the version the Zeta cars would get. This motor will start production in
first or second quarter of 2010."
I am not getting to excited yet but from what I know and what my friend tells me (Corvette owner) that site has reliable info.
This may be an early leak to what we might find out (its valid) once the "you don't want to miss November" news is posted tomorrow on the Chevy Nation site.
Again, its still a rumor until Chevy/GM announces it.
