2002 with injectors... You are walking the very edge, with good tunes, your ok to about 400hp, but with PMR rods I would not push it past 350...
Ford changed the Rods in 2001 to powdered metal, Weaker when not designed to be PMR's from the get go. The 6.0 Diesels use PMR's but they were designed to be that way.
No, the 7.3 is far from bullet proof. There a workhorse no doubt, but you start modding them, they will break.
