The reason you haven't been able to find any info on a "miracle" rod for the 292 is because so far, there hasn't been one found. Not that one would be a true "miracle" rod, short of a custom billet rod, but one that will bridge the gap for where the stock rods falls short. The stock 292 rod is very undesirable for the elevated power levels and RPM that can be easily obtained using todays modern performance components. The Jag and GMC rods have been discussed before as being likely candidates for swapping into the 292 engine, but different issues prevent each of them from being used successfully to do this.
The aftermarket has provided solutions for the 250 engine with making available several different inexpensive race quality I-beam and H-beam rods at a cheaper cost than custom billet rods, but for the 292, there hasn't been any such aftermarket parts made for the 292, only custom $1000+ rods, making it very expensive to build a 292 for high performance use compared to a 250 engine.
