Did the engine stall or run rough before dying? Or, did it just stop running? If it ran like crap for a bit, you may be ok. Hydrolock doesn't take much water and as said above can do some serious damage. Usually on the VG30, it will bend a rod. But, could be worse, may not be a problem at all.
I would pull the plugs to start, and see if you can get the water out of the cylinder. After you do, then crank the motor by hand. See if you get any significant resistance. You want to pull the plugs to keep from hydrolocking the engine if you haven't already. If it seems fine, then try to crank it with the starter. But, pull your fuel relay first, that way it won't shoot fuel into the cylinders.
If this is too much for you to handle, then have it towed to a Z specialist. Don't have it taken to some average mechanic. Most don't have a clue how to work on these. It isn't you normal Ford, Chevy or Chrysler.
