Piston Rod info

Anybody ever seen this?

Is it acurate?

I've heard of guys breakin down motors made after 01 and finding forged rods but...

Here is the engine serial number break down for the forged and powdered connecting rods. Check you engine serial number on the valve cover build sticker or you need to look at the block where the oil cooler is bolted to it .
Start of production thru 1425746 are Forged Rods
1425747 thru 1440712 are Powdered Rods
1446713 thru 1498318 are Forged Rods
1498319 thru final production run are all powdered

I looked through the inspection hole on mine..Not forged here

Do you know your motor SN?

I'm curious to see if this list matches up.

I checked it against the # and yes it confirmed it.I was still curious and had to look though.

so i guess the forged rods would be better than powdered huh?

[chvyrkr81]

With proper tuning forged is holding over 600.

PMR is only "safe" for around 400.

my # is 1847089 which isnt on the list

[chvyrkr81]

Yeah this is 7.3 specific.

All 6.0's come with PMR's. I don't know enough about the 6.0 to do anything but speculate, but either the PMR's in the 6.0's are made stronger, or the smaller diameter piston doesn't create a problem.

I've seen this list a few times now. Can't say how it stands up, best of luck to ya'll 7.3 cats.

Yeah, I'd kinda like a few guys that KNOW they have one or the other to join in with their motor SN and see if the list matches up.

I'm especially curious about the motors where the numbers go back to forged after bein PMR for 50,000 or so.
