I'm not sure what power level it would be at, but i think the limiting factor(considering a good rotating assembly) would be when you reach enough compression/boost and you start to pull the head bolts out of the aluminum block.

The heads lifting is the only thing I would worry about with an aluminum block, and I'm pretty sure that, that problem can be eliminated in all but the most extreme situations by better design from the factory. I dont think you'll see any heads lifting on the aluminum warhawk block.
I would imagine that an LS1 with a forged internals will take 1000+ hp and if your really worried about I would think that with some darton sleeves the LS1 would be damn near unstoppable.

Harlan has pushed his AL block and stock crank (I think stock crank) pretty damn hard. If I was to say what block was stronger out out the LS1 and LS6 block it would be the LS1.

lifting isnt an issue anymore if done correctly, and it would be an issue even on an iron block.
I am not quite sure i understand the question about the windage tray , are you refering to the spacing or the use of?
The only thing odd about it , is the fact i have it coated. that was done for drainage and foaming.

I suspect the windage tray only goes that far due to the minimal distance from the crank to the bottom of the pan in that area. It stands to reason that you won't see a great deal of windage in an area that's too shallow for a large amount of oil to pool up. Just my .02
