Alan, they already have a all aluminum 455 cu inch 4 cam V8 designed for it. Translate that into cc's of displacement
at your own peril! This motor is not be a stroked version of the 350 V8 like the Z06's 427 is. It is a lightweight big block motor. Without turbocharging or supercharging, it could easily achieve 575hp-625hp and have a 8000 rpm redline. It would make the current Z06 engine sound and feel tame. Think back to the big engine Can Am cars, its that kind of power and volcanic torque.
