6.0 liter???
That doesn't really make sense does it? Unless we're talking something we don't know about... Gen V(they aren't supposed to be ready in time for the camaro)
As far as engines we do know about, the LS2 or L76 are 6.0L but the LS2 has already been eliminated as an option.
So we're left with the L76 as the only "known" V8 engine... Hmmmmm I'm not sure how I feel about this just yet. The good news is we know that 400 is the minimum V8 hp number and that's a great start.
