The LSA goes with the diff, rear end etc. I don't think you would see one without the others.
The current 340 LS3 is the most powerful LS3 in the GM world (from memory) so i wouldn't expect much more.
Whatever the boys are planning in next update, i have no doubt it will be worth waiting for.
Hopefully its enough to keep my dollars local cos the euros have some nice stuff coming and im really liking the look of the new C63!
