In GM's case, they are already starting out at a larger 6.2L, and the small block can go up to at least 7.0L, so it won't need as many revs.
And, the LTx is now DI, which means you can go higher compression as well.

I was just playing devils advocate, as a lot of people in here make it sound like it would be super easy to do another 7.0 and have it make 550+

Why is it that companies like Lamborghini make cars with only V10's and V12's that get an absolute max of about 20mpg? And were trying to figure out a V8 in a limited production car? wouldn't the mileage of both the V6 and I4 offset the impact of something large for the Z28?

I think some peopel have thrown CAFE out there, but it is more on the emissions standards IIRC
