More than it's worth. That's a big shot, and the big damage can occur when you don't have the fuel to match it. You can go alot of different ways, but any of them will be expensive. If you've got a stocker 305 -- You'd spend a ton getting the motor ready to handle that kind of a shot of nos. That's the non-technical opinion -- let me know if you want details

Fuel supply will be critical!!!
That being said, forged pistons would be needed to be safe, preferably with ceramic coating on top.
A forged crank would be a very good idea if you want it to last.
As far as rods go, at a bare minimum You would want to use a polished "pink" type rod, meaning magnifluxed, beam polishing, good bolts, resized, shotpeened, & magnafluxed again. Better yet aftermarket I or H beam rods.
You could probably get by fine without a four bolt main conversion, but it would be reletively cheap to do it while rebuilding.
That should set up the engine enough to swing it.
At that level of nitrous HP you would be better off with an individual port fogger system, especially if you are using a TPI, or dual plane intake.
It would also be a good idea to use an RPM switch to control it so that you don't engage it at too low an RPM and over fill the cylinders.
All of that would be kind of pricey, Not to mention what you would have to do trying to hook up all that instantanious torque.
have you considered a smaller shot, maybe a two stage system?
