For a long time I was a die hard 7.3 owner, but I kept having problem after problem with it. Costing me a couple grand each time it puked on me, stranded me a couple times. I had buddies who had 6.0s and I was skeptical after seeing all the problems with the 03-04s. Finally got tired of the old 02 7.3 and found an 07 already studded and everything i wanted on it. I've had it almost a year and wouldn't ever considering on going back to the 7.3. Never had a problem with it. It is a tempermental engine but once you get familiar with it, they're easy to get around. Best truck I've had, pulls my 10k stock trailer with no problems. Buy it, delete and studs, tune...and drive the piss out of it!
