Powerstroke 7.3L Connecting Rods?
I had a long discussion the other day with a gentleman and he questioned if the Powerstroke uses "Powder Metal" or "Forged Steel" connecting rods.
I was told that if in fact the Powder Metal Rods are used, any additional hp/torque other than stock would be most detrimental to the health of the motor?
Anyone out there have an idea?

The answer is: both. Pre 99's had forged steel, the Super Duties have powdered metal. The fact is, it's a myth about powdered metal being inferior. It's been proven to be superior to forged steel in many ways.

Ok im going to add to this. Pre 99's were all forged. 99-2000 (actually a build date of right around Oct. 2000 on the motor) were all forged. From 2001 to present the Powerstrokes use PMR's as some guys call them. There has been lots of talk about forged vs. pmr's over on the diesel stop. Im sure quadzilla has read about that. Mainly forged rods can handle more HP than the PMR's. There have been some cases of PMR's windowing the block when you throw alot of power at them, i.e. big HP chip + propane or nitrous.

I asked a Ford technician whether my '01 PSD had forged or powdered metal rods (build date Oct. 2000). He said, according to his service manuals, it has forged rods. It is my understanding that 7.3's have forged rods and the 6.0's started using the PM rods. I read an article about the PM rods and feel thay are pretty reliable. They have their advantages.
