Just for clarity sake, the forementioned cat engine only produces trq rateing's in the 400 to 600ftlb range, in stock trim.. This would actually be less then what the 400/450hp cummins will produce .. I too very briefly considered the divorced 205 in my upcoming f450/dt360 conversion, but fiqured it wouldnt handle the weight,or trq the truck will be towing/produceing.. As it stands a transfer case option, and time for the project is my only hang up.. Pondering a way to divorce the np271 in the truck now, or move up to one out of a military m35 2 ton..
