I'd be surprised.
GM hasn't done a power bump since the ls1 and ls6. They get an engine and stick with it.
I'm guessing emissions and or mpg is holding them back. The cam in the lt1 is smaller than the ls3. The could easily revise the intake for a bit more hp and rpm as well as a slightly larger cam. Keep roughly the same torque and increase the hp by about 20 imo
I think gm is looking toward the dohc 6.2 if I had to guess. It will be a monster having best of both worlds cubes and high rpm
Other than the 10 speed I'd be surprised if the SS gets any strait line improvements this gen. But I'd love to be wrong
