You never mentioned whether the converter is locked or unlocked. That will make a huge difference in dyno numbers.
I'm going to say somewhere around 780 HP with the converter locked and a very conservative tune.

Just going by similar setups I've seen
Through a 60 mine made 730 at just a little less boost
We have fairly similar setups engine wise, I'm using two cheap turbos, he's using one nice one. Figured his would dyno a little higher with 2 more psi, but would lose just a bit more drivetrain wise.
Post up a graph when you have it done, don't see that many people use those turbos, be nice to see how it compares to something similar in size
