That is the LS9. Supercharged 6.2L.
The CTS-V is using a slightly modified LS9, called the LSA - which is interesting as it is...
*EDIT* Straight from wikipedia:
The supercharged 6.2 L LSA is similar to the LS9 and scheduled to debut in the 2009 Cadillac CTS-V. The LSA has been SAE certified at 556 hp (415 kW) @ 6100rpm and 551 lb·ft (747 N·m) of torque @ 3800rpm. GM labels it "the most powerful ever offered in Cadillac’s nearly 106-year history". The LSA features a smaller 1.9 L capacity supercharger rather than the 2.3 L variant of the LS9. Other differences include a slightly lower 9.0:1 compression ratio, single unit heat exchanger and cast pistons.
Gah...cast pistons. So to reep the full benefits, you'd need to swap the bottom end and swap the blower. Bam, you have an instant LS9 for the most part...
