I've got Billet I-beams for it. I'm not worried about blowing a rod. It's built for 25psi. If I stayed with an N/A 6.1, I'd have no problem running a stock 6.1 Rod out to a 6800rpm shift point all day long.

Over 7k and 600rwhp, the rods can be weak.

I'm not suprised that dirt track motor threw a rod. Nobody should be awestrck by that.
