I daily drive a stock 606 turbo in a W210 and it doesn't drive anything like a 1600rpm torque peak. More like somewhere between 2500 and 3000. It does not push the heavy Mushmobile around very well at all at 1600 rpm.

My amazingly reliable and irrefutable source for the info at hand was http://en.wikipedia.org/wiki/Mercedes-Benz_OM606_engine

Ahem. That said, I'll definitely be putting the engine in the truck in front of the stock differential gearing and doing my own driveability testing before putting money and time into regearing for highway travel.
