The 7.3 is a fairly reliable engine but it does have weak spots. I have driven 1 or 2 but never owned one. I have a 6.0 F350 as does my BIL who said he would never go back to the 7.3! You will most likely need to consider investing some $$ to get the thing reliable such as new exhaust bellows and a better intake from what I have read. Some tuners can help quite a bit. Go view some of the ford diesel sites and read up is the best advice to get. BUT you said you were familiar so you should already be prepared for whatever comes about.
Exhaust bellows... Think you mean the up pipe's. Not an issue if maintained correctly. Same with the turbo pedestal and the cold start assembly. Easy replacement on both. Trick to the up pipes is keeping road spray off them. Mine are protected by rubber splash shields, never had an issue. Turbo pedestal has been replaced with a Garrett delete pedestal long time ago.
All in how they are maintained. I know how mine is maintained, I bought it new in 1997.
6.0's have head bolt issues and EGR issues and the cab must be removed to access the head bolts on the passangers side bank.
With any older motor, expect to replace stuff. I had to install a new injection harness this year. Things get old and fail.
