Seems like you know a LOT about the Camaro, Mike2010.
Are you a Challenger fan, owner, future owner, ........or just stirring the pot with this - your first thread?
Why would Chevy throw the LS7 in the Camaro? What would that do to Vette sales?
That's like Dodge putting the SRT10 8.4L engine in the Challenger. It would help Challenger sales - and kill Viper production.

You can bolt on more horsepower easily to ANY car. It's just a matter of dumping $$$ into it. HP numbers will change from car to car for every Mustang, Challenger and Camaro that hits the road.
The way the car looks is what you really can't change much.
The Challenger is the BEST looking car on the road (shy of a six figure exotic). The Camaro can't touch it in that department. The Camaro was designed to appeal to the ricer crowd.
