I thought I read somewhere that GM still has a surplus of LS2's and will most likely use those for the '09 Camaro. The '08 vette has the 6.2 LS3. Now they may upgrade the vette for '09 and throw that LS3 in the Camaro SS. Sounds right.
I believe that we're going to get the LS2 for the first round of Camaro's until they're completely used up or just "fade away".
Either way, I plan to buy the Camaro when it's released. If GM plants a significantly more powerful engine in later models, I'll just trade the '09 in.
