It actually says in the Camaro Owners Manual (page 9-56) that you will get reduced performance using less than 91 octane in the V8s.

"If the vehicle has the 6.2L V8 engine
(VIN Code W) or the 6.2L V8 engine
(VIN Code J), use premium
unleaded gasoline with a posted
octane rating of 91 or higher. For
best performance, use premium
unleaded gasoline with a posted
octane rating of 93. You can also
use regular unleaded gasoline rated
at 87 octane or higher, but the
vehicle's acceleration could be
slightly reduced, and a slight audible
knocking noise,"
