This according to the Detroit Free Press today 12/3/10.
Looking like it's getting closer with
info coming from the RenCen tubes!!
Chevrolet will revive its high-performance Camaro Z28 as a 2012 model,
giving it a supercharged version of the current
Camaro SS V8 engine with between 500 and 600 horsepower.
