I think it would be a easy swap. The bellhousing fits the same. They all mount from the sides. If yours mounts up front you will have to get a crossmember kit. Chev. never put it in anything bigger than 1 ton. but it will stand up if you don,t work it to hard. We have a 6.2 in a rollback & go all over the midwest hauling cars & pickups. It,s the 2n,d engine in it & must have 3-4 thousand miles on it.
