Sounds like the SSR is shaping up to become a serious performer. Maybe now the price can be a little more justified.

Also to clarify things, this is the second version of the LS2 the RP has alluded to. To be honest in simplest terms the LS2 is nothing more than an aluminum evolution of the LQ9 iron engine in the Silverado SS with Gen IV upgrades. This means that while the iron 6.0L will continue in the various truck apps, all performance versions will have the aluminum 6.0L and referred to as LS2 (a nice marketing ploy). It will likely be rated in the neigborhood of 380-390 HP with more tuning towards TQ nd be used in both car and truck appliactions. This shadows GM's treatment of the LS1 when they had the 350 HP Vette LS1, and the "slightly detuned" F-body LS1....only now they are sharing 6.0L with truck apps and further spreading development costs. The LS2 will next year be the top engine in the C6, so IMO I would not expect the SSR or any other LS2 powered vehicle to carry a 400 HP "rating". Expect to see this new engine in the Trailblazer SS (the SSR is a Trailblazer, so this obvious), Silverado SS Shortbox, and........(sit down).....possibly the high performance GTO.

You heard it here

Thanks for the info, will this second LS2 (LS2a) have a lower readline like most truck engines seem to have? What gives it the low end torque boost, different cam or PCM?

I know where you are coming from. Same thing happens at my level too. Only thing I am saying is that when I hear it from the official product teams that tell you when they want you to know, I will generaly get that info pretty quick.
