Hi fellas

I am thinking of purchasing a 99 longbed with a V10 as I think I can get a steal on it. Currently I have a 2001 shortbed with the 24v Cummins. It may sound like more work than its worth but I would like to swap the drivetrain's on these two trucks. I have found that my family and I would like the room of the long bed for the stuff that we do so this may be the perfect truck. I hate to asume, so I am asking for confirmation. Can I take my Cummins engine with the 47RE and transfer case as one asembly and drop it into the long bed truck as a direct bolt in replacement? The long bed has the V10 with the 47RE and transfer case, and I would probably put that drive train in my shortbed and then try and sell the truck. I am asuming that the frame's are built to take either engine but I dont know that for sure. If I have to do any welding and fabricating of engine/transmission mounts then I dont want to do the project. Also, does anyone know what complications this causes to the vehicle title and State emissions and inspection stuff. I realize that is a question more specific to my State, but I am just asking in General. Thanks
