7.3L durability

On Average, how many miles will a 7.3L provide reliable service?

Im trying to calculate what % "Used up" a 7.3 will be based on mileage to help figure out what to offer when purchasing.

About 150k is when I needed an injector and shortly thereafter the trans was toasted. Luckily I found this site so I got a BTS trans.

I don't think there is a way to determin by mileage. If it breaks, fix it and keep going. I have 115,000 with no problems besides the normal things. Tires, small leaks that are easy to fix. Huumm.

I have 135000 miles, and I can't answer your poll because I haven't had any major problems yet.

I'm at 75k on my '02. Batts & alternator are all I've had to replace that were bad. Other than that, oil, fuel filter, and MODS!!

EDIT: I had to replace the O-rings on the fuel lines going to the filter bowl. When I installed the CCK, they were pretty ugly. To the point that the return line was leaking after the job. No problems since.

I have 136000 km's about 83k miles. Nothing big has come up yet , but i've had to replace the cps 4 times. And everytime I tow the OD light flashes. So im planning on getting a bts tranny soon. But other than that, i've had no problems at all.
