question on the 7.3 internals

[Michael H.]

ok i am looking in to getting a new engine for the truck to make more power. i was told that my rods will only handel 450hp. so my question is which year did they have the forged internals in the 7.3's ? where would my vin on the block be so i can tell if mine has it or not?

thanks guys

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
So far, that numbering is right.
Also, there is an inspection hole to check them.
Lots of threads on this.
You SN on the block is on the passenger side valve cover, assuming it hasn't been changed for a different VC.
Also, there has been better tuning and I think there's some >500HP trucks on PMR.

those numbers will be on the valve cover? and you say there is a check hole? where would that be at?

thank you very much for all of your info

been out looking at the vc and cant find the number. it looks to be the original one. says its for a 2000 which is the year of my truck. been looking fo a few min's maybe looking right over it.

is it on the green sticker?

I told you wrong. It's on the drive valve cover. Forgot there is one on both covers. Pass side has year and HP/TQ numbers.
Driver side is the SN. My bad.

[Michael H.]

SH!T!!!!! that was what i thought.. the sticker has been ripped off.. CRAP!!! any where else?

[jesilvas]

As far as SN, no.
Let me find the thread for the inspection hole.
