So the other day my uncle bought a 08 cargo van with the DMAX with 400k miles on it. The motor is in good shape but the body of the van is shit. We were going to swap the duramax out of the van into a sierra or silverado. Anyone know how hard it would be to take that motor out of that van and put it into a silverado or sierra? It would most likely be a new body style truck, but if it is possible do the LMM series fit into the classic body style?
