Default Stock crank and HP?

Seems there are many different perspectives on how much HP the stock crank can handle. I want to try pushing the limits with a nitrous 2 stage. Close to 400rwhp NA with a another 200rwhp of nitrous. The plan so far for the shortblock is, studded 2 bolt mains, short-fill, and only going .020 over with the nitrous pistons.
I will have rods and pistons that are up to the task. Plus I don't plan on spinning it more than 6400 rpm. Anyone here ever try something like this? Any suggestions other than it can't be done. Thanks, Rick.

See, thats what I'm talking about. I've been told, unless you spend some decent money on a crank, just to keep the stock one. Now you have gone faster than I'm hoping for, with a cast scat. I'll do a six point, but no cage.
