I had a 2008 F350 with the V-10. The motor is light years better than the 6.0 diesel in terms of reliability. The only downfall is the spark plug design in the 3 valve heads. Ford is very aware and very ignorant of this flaw. They actually redigned the heads in late 2007 to correct this issue. I did a quick search and any V-10 built after 10/9/07 should have the updated head/plug design. My truck was an early 08 (built in April 07). If you want the best possible V-10 scenario I suggest buying a late 2008 or 2009 V-10. That will eliminate any spark plug worries. If your limited to an 05-08 V-10 expect plug issues. FWIW I loved my V-10/Torqueshift combo. I just had to many issues with the rest of the truck so I ditched it (well before I needed spark plugs).
