F 250?

I would not recomend a 6.0 or a 6.4 to anyone. They are absolute junk. I was going to buy one of the new 6.7s but I talked myself out of it. I want to see how they're still doing in a couple years. You just can't go wrong with finding a good used 7.3. We've got several 7.3s that are going on 400k miles and dont use a drop of oil. Have been pulling HEAVY trailers and idle all day since they were bran new.

The main problem with the 6.4s is the radiators. I have put 4 radiators in mine. 2 sets of EGR coolers, 4 sets of injectors, a starter, and it's only got 80,000 miles on it and my wife drives it to work everyday. With our business, we have bought about 10 6.0s (Blew the motor up in every single one of them) and two 6.4s (blew the motors up in both of them). We have had probly 40 or more 7.3s and maybe had to change a motor in 2 of them. Got several we bought bran new in 95 that are still going wide open everyday.
