Also I reckon a BMW 535d engine would be pretty impressive. A 3.0l inline 6 Turbo Diesel with 272hp and 413lb/ft of torque (thats not a misprint ). Bolt two of these engines to a common crank in a v12 configuration, and I would have one under the hood of my F-350 in place of the PSD... This engine (the 6 cylinder) came 4th in the Paris Dakar rally in a BMW X5, so must be pretty reliable...
