Here's an article from carcraft, not much tech just destruction but gives you a hint at how tough a SBC is.

That's a good article.
Main thing I've learned about hypereutectic pistons is they have a higher silicone content. They're not much weaker than cast but don't hold up to heat as well. So either way your durability would be about the same when it comes to nitrous.
If it was pinging like you said it may have weakened your pistons a bit, a nitrous shot might be enough to break something that's already a little stressed. However with this being your backup backup dd I'd say it'll handle it lol. Just keep it fueled up n keep the timing right, the amount your looking to spray shouldn't have any force like the one in the article lol unless you hit it in low RPMs

I was always under the impression that CAST was fragile.
