"We recently came across some interesting information from a credible source about future products for GM's Chevrolet and Cadillac brands, and which to some extent, are interconnected.
We'll begin with Chevrolet as we learned that the Corvette's immediate future includes a more potent version of the 4.5-liter twin-turbocharged and direct-injection engine that GM debuted on the Cadillac Elmiraj Concept just last month.
We're told that the new V8 will most likely be used in the successor of the Z06, rumored to be called Z07. While in the Elmiraj, it produced an estimated 500hp, in the Corvette, it could push out as much as 600 horses (unconfirmed)."
Sounds interesting!
