Recently I joined a Ford F150 forum since I bought a 93 F150 some three weeks ago. It features a fuel injected 4.9 litre, 300 cu. in. inline six cylinder, some 1.9 litres bigger than my OM603, but a gasser!
By comparisons, the 603 is much much faster, but the Ford has low end torque, way low! At 1600 rpm, it builds most all of it's power (seems like it's lugging all the time) but I love it and have spent much time over on the F150 forum

The 87 300D is put to bed for the long cold winter and look forward to driving it again soon.........BB
