Yup, they revised quite a few things though, so heads won't be interchangeable from the looks of it.
DI, CVVT, DOD, and all that good stuff.
The block will likely have a slightly different architectural design too as the engine is now an LT1 instead of the familiar LS family. In fact, after next year, GM won't be furthering their LS family development. Sadly...
The LT1 name is a little annoying to me too. It was first used for a high performance 350 of the 60's in the Corvette. Then it was whored out in the 90's for the reverse cooling 350 in the vette, f-bodies, and B-bodies. Now this.
At least the DI means power upgrades won't require fueling upgrades for a while. But it will cap the more extreme builds and require extensive revisions to the fuel system north of 1000hp I imagine.
