Such a small rig could be fun with a 4BT, but absolutely nose-heavy. Maybe that 3.3L engine that Cummins outsources from Komatsu could be a better fit, even though due to emission laws it would become nearly impossible to register your truck with a Cummins swap (unless you could get that R2.8 crate engine which is still too expensive).
2wd Vs 4x4
2wd/car =6.125" index 12.25" narrow block cross the lower bolts at crankshaft Centerline
4x4 =6.75" index 13.25" wide block(same as Mitsubishi diesel)
Results un the bolts over lapping . This requires in an adapter thicker than the stick out on the trans input shaft.(results in no pilot bearing support, a no go).
Emissions
If you put every soul in Montana in one place we wouldn't have enough people to pollute the air badly enough to need diesel smog requirements. . Solved.
Nose heavy
Cab set back to ficilitate a more proper 40/60% (fore /aft ) CG. Plus longer/better nose fineness raito.
