A twin turbo, DOHC V8 makes absolutely no sense for the track star Z06. It adds weight in exactly wrong spot for such a car -up front and up high. Sure, you might potentially get more low/mid range torque ... but then again, the new LT small blocks are absolutely not lacking in low & midrange torque. There wouldn't be any real fuel economy gains (if thats even a concern) because you'd have to run so much boost to get 600 horses out of a 4.5L engine.
Odds are, this is either intentional disinformation from GM or some guy misinterpreting a piece of information.
As for the Cadillac ... I could see it getting a 4.5L turbochaged V8. Only I'd expect to see it as an oil burner instead of a gasser.

A NA 7L V8 would sound better, IMO. It would also sound better when you let off the gas -no sneezing.
