How Much Nitrous Can The Stock Pistons Handle?

The article came out in Car Craft magazine first. They didn't do article sharing like they do now, but the Car Craft guys got a stone stock 360 out of a junkyard with the intent on eventually blowing it up with nitrous. They kept putting more and more on it and I think they got it over a 300 shot. On a stone stock engine. It never broke. I'm sure some of yall remember it. The name of the article escapes me.
