The 4BT is a little small, but would have just the right amount of off idle TQ to get it done. He has really done some wild things to that truck. I would say a 6.5TD GM, 5.9 6BT Cummins or something along those lines. Early 6.5 is all mechanical, as are the 12V Cummins. He has a few choices at this point, but with a rock crawler, I would go 4BT, size weight ratio would be good for the most part.
