I was bored the other day and got to thinking about putting a 3 or 4 cylinder 2 stroke detroit diesel in a 1950 3100. What would be transmission options? It is only a 2wd but i was thinking of finding an axle of a 70s 4x4 and fabbing that up and using it. If I did take that route what would be a good transfer case? And what engine would fit the best?
