I am looking at a 03 6.0 and I was wondering what build dates, if any, should I avoid. I will run an OASIS on the truck to see what has been done to it. Any other things that I need to look for on the early 6.0's? Thank in advance for your help.
My experience shows most of the early concerns have been addressed. As long as you aren't "hot-rodding" the truck, everything should be good to go. Make sure it has the latest flash and service it properly.
