COPO "concept" is being tested with 2 different engines so it can qualify for 2 different racing series.
First engine is a supercharged 5.3, the other is a higher output 7.0.
Believe they are running high 9's with it. Not sure on what the CobraJet is running.

Funny story: In 1969, the ZL1 was a COPO car, yet 2012, ZL1 engine will not be available for COPO race car because of displacement rules.
