What is "throwing a rod"
I saw a video somebody posted on here of it happening and I'm pretty sure I don't want it to happen to me. I'm doing a head/cam package this spring and want to make sure I prevent any problems before they arise. Would hardened push rods help prevent this? What all forged/hardened components should I get?

But on a cool note. I would love to see a rod escape through the hood.. That would be quite a sight.

Re: What is "throwing a rod"
I asked the same question and ARP rod bolts were suggested to me, as I guess it's the bolt that usually stresses and lets go first, not the rod itself. Assuming your valvetrain is up to speck, the stock crank, rods & pistons are good to at least 6.5k (some push it to almost 7k) before you risk engine carnage.
When I do my heads & cam in the spring/summer, I'll be replacing the rod bolts, along with the cam bearings. I haven't really decided on the rod/main bearings yet. Guess it depends on if I have the time...
FYI your whole valvetrain should basically be replaced if you're going to go past 6k. The pushrods and valvesprings especially.

Where the block shattered, the heat was great enough that it then welded itself back together in the new configuration.

I've seen a video of a white Blazer a while back... supposedly they put a buncha everclear mixed with gasoline in the tank, and floored it up and down a street, and after a minute you hear an explosion and part of a rod and part of a piston flew straight up through the hood and landed like 50 feet away. Crazy stuff

Generaly when the rod breaks, that could entail sending it through the sode of the block. Its generaly not comming through the hood as it would have to clear the head, valve cover then the hood.
