what year did the 7.3 switch to the powdered metal rods, are these better than the previous or worse?

Late 2000 was when they switched. 2000 model year trucks built in 99 usually had forged, later 2000s, some had PMR's, some had forged. I think all 2001 and on are PMR. And the PMR's are worse. Bad. They hold stock power ok, but if you do much upgrading they will crack. Forged are good for about 500 HP reliably i believe.

10/2000 was when they switched but there was a series of trucks that came with forged rods into 2001 when the PMRs were not supplied for a few weeks. The ONLY way to know for sure is to pull the inspection plug and check for yourself. Bolt = bad, nut = better.
