Does anyone know if a 4 Cylinder can be used to replace a 5 cylinder, 14L engine. Like shaft diameters, etc.

The 4 and 6 should be the same at the rear engine mounts. You would have to reposition the front mounts a little farther back. There may be interference with the steering gear box. Fan to radiator will be increased with a decrease in cooling efficiency. Why the swap?
