I believe the 7.3 is the best powerplant Ferd ever placed in any vehicle!! That is why I have one. The 7.3 life can go well beyond 400K but it all depends on prior maintenance, just like with any other vehicle. You have never towed and enjoyed it like you will when towing with a 7.3. Somethings to look for specifficaly on the 7.3 are as follows.
Pull the lid off the airbox, if you see a K&N drp in filter, runaway!! These let way to much dirt in and have been known to dust many PSD's, remember dirt = death to a diesel!!
Take a screwdriver with you and pull the intake tube and shine a flashlight at the turbo fan, if it is chipped or the edges rolled over it means it has inhaled dirt = runaway!!
A thin coat of oil is normal inside the intake but there should be no dirt.
If the previous owner ran a chip or performance tune and didn't have at least a pyrometer runaway.
The 7.3 programming was tuned way down because of the weak 4R100 trans. The 2001 had the dreaded mechanical diode in the trans, just so you know in case you look at other trucks. These diodes would fail and Ford had to replace thousands of trannies, some say if a 2001 trans made it past 80K it was good to go, but???
If the PO has maintenance records it goes a long long way. I would run a Oasis report and a Carfax report. If the PO will allow you to take a oil sample and over night it to Blackstone Labs and get a expedited analsys done. This will tell you a lot about the condition of the engine. If he won't allow this , you guessed it, runaway!!!!
If I can help you in anyway just PM me.
