I paid 29K for the car a few years ago, so I would have nearly 60K in it. I would be happier with the 415, but the LS7 is looking like a sweet deal these days.
What interests me the most about this is our 350 can get close to the output of the LS7. That is what I am personally shooting for. I want to build the most powerful 350 I can. I should say, one day I will have Corey H do it for me though. I am no engine builder.

Not taking anything away from the C6 Z06 - I'll bet with its weight it would be a hoot to drive. But, back to big motors, I believe FBI'ers - Bob G, Al, and Kevin all built a 427, and two 441 LT5s - all of which would blow an LS7 away across the board. And, the tag was more like $20k - quite a bit less if you did your own porting and disassembly and reassembly.
The nice thing about building a big inch LT5 is much of it can be done in phases - providing some nice performance boosts along the way: porting the top end and timing the cams, and installing headers, for example, could net you a 500 hp 350. All those base pieces would transfer to the big boy (with some further porting and bigger valves, perhaps) so nothing is lost. With the sleeves and portability of parts, the LT5 becomes close to "modular"!
Sorry...My enthusiasm is leaking out again
