Actually, they were looking to use a supercharged version of some engine.. I can't remember if it was the same engine in the new Camero with a blower or what... But, it was suppose to push about 575 HP. This would be the new top dog Camaro. I think you can find it on worldcarfans.... I will see if I can find it...
Edit: Here is the link. I was off on the HP. Looks like they planned to use the CTSV's supercharged engine.
