Mine has been far from completely problem free (I may have broke some of it myself ) but, I love my truck still.
Mine was made 10-03...and had EGR and head gasket problems that Ford could or would not fix it. Glad its gone, but miss it......I would either stick with your 7.3 or go up to a 6.4. I will not have another 6.0 because of the reliability issues.
Why? The 6.4 is an unproven motor and it is only meant to tide them over till the "Scorpion" motor comes out. That is the in house motor from Ford.
what he said
late 06 build through 07 were pretty much fixed
however late build 05's also had very few issues
except for the hpop quick disconnect, but once it fails they fix it right
