The motor will be named "LT1" which most of us know has already been used. This will still be a 6.2L but with up to date technology vvt, di, and cylinder shut down (not on manuals woot!).

Here is the dyno sheet from GM and a picture of the motor. At first I was not impressed with the peak numbers of the LT1 but the horse power curve looks good to me compared to the LS3 curve. However it still says projected. The TQ curve is close to the LS7 curve which definitely excites me.
