I recently purchased a Case 855E. It has a hole in the block and in the oil pan. I have a 6BT out of a Dodge Cummins Truck. I wanted to know if the Blocks are the same and if I can use the Dodge 6BT Block and swap all the parts from the Case over to it and use it. I have access to a 6BT that came out of a Bus, and one that came out of a Generator. Do you know the best route to go? Thanks Carlton
