2000 at the flywheel? Yes, I think so.
My son-in-law's, inter-cooled, twin-turbo LS2 stroker 402 puts down huge RWHP on "Moderate Boost" 10 PSI, it can run up to 21 pounds with small turbo-netics turbos.
See it dynoed on the Video:

This video is with the old Danzio Motor in it, he's since gone through and built a new LS2 motor with quite a few significant improvements.
You can see this is a couple years old and the technology on this 2000 Hp LSX looks more sophisticated.
