NO, you cannot trust the early build 2003 6.0, even after bulletproofing... My 2004 with leftover early build 2003 6.0 (quite possibly the worst engine ever put in any truck ever) has been bulletproofed and I still have problems with it, I can't trust it, and that's with 88,000 original miles... It's currently down again with another Camshaft Position Sensor signal failure (either CMP sensor again or the pigtail/harness this time)... It's on it's 3rd Turbo, 2nd FICM, 2nd CKP sensor, 3rd set of Injectors, 2nd Injector harness, 2nd water pump, 2nd clutch fan (this time a 7.3 fan and adapter), 2nd Intercooler, 2nd set of CAC tubes/boots, 3rd VSS Sensor, 3rd ICP sensor, 2nd IPR sensor, 2nd engine (first blew at 31k miles due to failed injector)... IMHO, do not walk away from an early build 6.0, RUN AWAY FROM IT... As fast as you can, and don't look back... With this engine, once you fix any particular problem, it's not long before any one of myriads of known issues will creep up and you'll play the game of break down, fix, break down, fix, break down, fix, rinse, repeat until you finally throw in the towel and give up, but not until you have spent $$$ Thousands of dollars in the process... Don't believe me...? Take some time and search this "6.0 Engine and Drivetrain" forum and look at all the problems this engine has had over the years... If for some reason you decide to ignore this advice, first thing I would do is go out and buy the Autoenginuity Diagnostics Software, load it on a laptop and get real familiar with how to use it and how to diagnose your engine, 'cuz your gonna' spend a lot of time using it trying to troubleshoot all the problems you are going to have... I would also install a Scanguage II monitor, load all the additional PID's for the 6.0, and learn how to use the SCII to diagnose all the known issues when you break down 'cuz you are gonna' break down... It's not a matter of when, it's a matter of how often...
