The LS2 (the C6 engine) is rated at about 400hp/400ftlb, vs the LS1 rating of 350hp/360ftlb.
The first series LS6 (as I have in my car) is 385hp/385ftlb, the second series LS6 is 405hp/400ftlb - that puts the new C6 at about the current Z06 spec.
The new C6 also weighs about the same as the current Z06 - so performance would be very close.
Let's hope the LS7 makes good on the 450+ promise.
