Must be a 6.0....:D Nice looking truck, similar to my Dodge's color scheme, I don't have a pic of my Dodge, but it's similar colored in a Quad Cab 4x4 w/ a CUMMINS!!! Ironically in Ford HEAVY DUTY (F450 and F550 series) if you ordered the high dollar package you could get a CUMMINS instead of a Powerchoke back in the mid-2000's. :D
