Ditto on the torque! I believe that 1800 RPM torque peak is just begging for a little taller gear to let the engine grunt a little. Just don't lug it down enough to let it start detonating- - - -that will melt pistons in a hurry. If you can find a medium-sized Brown-Lipe auxiliary transmission and turn that 4-speed into a 12-speed, that would give you all sorts of gear ratio choices. Being able to split every gear up or down, plus a direct-drive choice gives a medium-duty truck all kinds of options for load-pulling and top end speed.
