So I have a bunch of Ford trucks with the 6.0. I have personally bulletproofed them all and I know this engine inside and out. We have been looking for a regular pick up truck for a while. My quest was a 3/4 ton, 2WD, 8' bed. Didn't care about anything else. We just needed a truck. Well, I was told about a possible sale from a friend. So I called this number and the guy says he is selling two trucks and they fit the bill I'm looking for. So we arrange a meeting. It is an old timer that is closing up and getting ready to retire. In fact, two old timers that are friends. They are both selling the company trucks. So, they are selling, 2 -Ford F350, 2WD, 8' beds, both with 7.3 Powerstroke Diesels. The trucks are 2002. Both trucks are around the 140000 mile mark. I brought my friend who is very up on Ford diesels. He climbed all over these things and took both for a ride. After that he says, buy them both, lol. So I did. Each truck was going for 5 grand but I walked out with both for 8 grand total. They are even red which is my company color. Both trucks are XLT so they're like Cadillac's compared to our XL trucks. Everything seems to work great and they are now in my yard. Each truck has to get a trailer hitch installed and a bed liner installed but I am OK with that. These trucks never saw a hard day in their lives as far as I am concerned. So my question and request. Can you guys give me some pointers on these truck engines. I don't have much experience with the 7.3 so I want to do it the right way. Thanks in advance.
