DOnt forget to add 2 or 3 grand for a dry oil sump system. Let alone a place to put that huge oil tank.
But what the heck it is only money
lets put in an X-Trac sequential gear box too.

You still have to consider that the LS7 uses dry-sump oiling system and butterfly valves in the exhaust system that open at WOT to get exhaust flow up. The battery is mounted in the trunk. I believe the engine mounts are different and the exhaust headers will probably not match up to the available space. With the new PCM (and lack of tuning capability until it is released) I would figure you can make better power by modding existing LS6 motors. No big reason to swap to a 427 LS7.

because of the dry sump, and alos to help weight distro, but mostly because of the dry sump. But the same can be accomplished witha battery relo. kit on a C5.
I have not heard of a mount change, so I don't think this is the case. The exhaust port location is the same as other heads, so headers aren't an issue AFAIK.
you can use your existing PCM. There is no way an 346 ls6 with a head flowing 100 cfm per port less on the intake side is going to beat a 427 with better internals, etc...

No but 346 to 422 vs new 427
I'm not betting 427 here
