Honestly although some may not like to admit it in the face of the dmax, the 6.0 is a pretty damn reliable engine, and has a hell of a lot cheaper upkeep costs than a dmax.

I would Highly suggest against a dmax swap by someone without experience, there's a hell of a lot more than one could imagine involved in the swap, and once you believe you have everything, you'll find a hundred different things to add.
If I were to do(have done) the swap it would be predator to do it, I've done engine swaps but to hell if I would take on this.
What they charge to have it installed, parts, labor, testing, is in all reality a damn good deal.
