Exactly what he said! 6.0's are good engines once you address all the common weak spots. They are more delicate then a 7.3 but they run so much better. I love a 7.3 and their tough engines, but their slugs compared to a 6.0.
Just about every model year of the 6.0 was a little different. A lot of people say the 03 year was junk but I disagree. 03 and 04 model year engines have some issues with high pressure oil pumps, but they don't suffer from the STC fitting issues that plague 05 up engines. Also 03's have much less issues with EGR coolers then later years.
Since an 05 model year engine was never offered in the excursion you don't have much choice anyway. You are either going to have an 03 or 04 year engine so it doesn't much matter.
Personally I love the Excursion and have been thinking about getting one for awhile. If I was going to get one it would definitely be a 6.0.
