5th Gen Z28, Gen V Engine.
Here is a picture taken of the new Gen V 5.5 liter C6R engine. I am pretty excited because I have not seen the engine at all before this picture. This was taken last month by a GM fan.
I will dig up some stats and what I know so far. Just real quick though, this engine produces 470hp and currently is a 5.5 liter. This is the engine I believe should go into the Z28.
