I'm gonna have to think that LS7 has had some internal work to make that amount of power under boost. All of the vette shops I deal with won't go past 6 maybe 8 pounds of boost without dished and forged pistons/rods/fasteners at a minimum...
The LS7's aren't really designed by GM for big boost.
as in LS2 or LS3 cars and LS7 cars on stock motors.......the LS2's/LS3's can actually make more horsepower via boost than the LS7's untouched. (usually around 600/600 on Z06's with meth, and upwards of 700 on untouched LS2's on the edge, LS3's they haven't had anyone that nuts yet)

It probably is a purpose built LS7, but even a stock LS7 shouldn't have a problem making those numbers with a cam change an 6psi of boost. Due to the compression I wouldn't want to put more than 6psi to an LS7 either. High compression and low boost does work out well though for power numbers and drivability.
I had the same thought for the coils.
