I think GM knows they can't really play in this class anymore with pushrod engines. Which is why I am anxious to see what they do with the real V-series cars. I would be perfectly happy with an LT1 powered ATS-V, but those who are cross shopping the M3 would look at that as an antiquated dinosaur. They would be wrong, but that is still how they will see it. I am guessing at a tuned version of this engine, about 450-470 bhp. The real question is if they will keep on with the LSA in the CTS-V, or if they have something entirely new up their sleeve.
