2003 7.3L Haa haa
I went out of my way to locate one and I am glad I did. My buddy had a host of repairs and Ford eventually bought it back and sold him another. I would have walked at that point and told them to keep it.
I am sure the problem has been fixed, but you have to admire the low end torque and the fact it is scrubber/egr free.
I dont drag so the 1/4 doesnt do squat for me...
If I had to choose between a 6.0 and a old school cummins...I would choose the cummins. IMHO of course
