I might be wrong, but I don't think the camaro has ever come in just one model of v8...and if it did, it wasn't for very long. I mean look at how every other car company making pony cars is doing it. Dodge Challenger - Base R/T and SRT8. They only have a 55hp difference but the 6.1l has much more potential than the 5.7l. Ford has their base GT then the Bullitt[spelling?], Regular Shelby model, and they have the Shelby Cobra model, along with a few KR's. So really, GM would be missing out on the crowd that wants just a little more ponies[or in the camaro's case alot more ponies] in their car and is willing to pay more for looks/suspension/power
