Question: Engine swap

Engine swap C6

Has anyone ever swapped out the base 6.2 engine for a 7.0? And if so was there any modifications to the chassis needed or is it a direct fit?

In general, the LS7 would be a "direct fit" replacement for the base LS3, but you'd be changing a lot of other stuff besides the engine such as exhaust, engine controls, cooling, and probably parts of the suspension and driveline.
