hope you have a strong engine stand, cause all diesel motor engine stands mount to the side of the block instead on the sides

Put something under the front of the engine to help support it. The Cummins is a very heavy very long engine. Even though it does not weight 2000 lbs the length of it will put ALOT more force on your stand.
