Looking for info on 2406782 rods

MP used to offer them. Impossible to find now. I have two sets of the smaller, lighter rods. The old 273 and early 318 rods that are bushed for floating pins. To my knowledge though, the thing about them being stronger was a myth. I've heard that too, but my understanding was all MP did there was take the factory rods, shot peen them add new bushings and good rod bolts and weight match them. There's no argument the shot peening process certainly makes them stronger, but AFAIK, there were never any "new" forgings made. I could be wrong.....but that would have been a huge undertaking for such a small market that those rods would have represented. They were plenty strong right from the factory anyway. They would have been stronger than the Pink rods the Chevy guy all have wet dreams about the way MP prepped them anyway. Probably good for 750 HP I would imagine. I wouldn't be scared to run them at all.
