To spray or not to spray

Hey guys, A family friend mentioned to me today that he has a complete nitrous setup that he would hold for me if i wanted it. How bad is it to run nitrous? I have a built 360 around 400 hp. How much hp would i gain from it.??? This idea would be for further down the road but i dont want to pass up on a sweet deal. It would never see use on the street only at the track.

my advice is to read everything you can get your grubby little mits on, this means everything-books, manuals, articles and what ever you can find on your computer by doing a seach. this way you can make an informed dicision. you will also find everything about pumping, wiring and all the safety parts you'll want to consider.
