Brand new, 2024 model year Mack MP7-395c Engine. It was a factory take out from a brand new Mack Anthem that we ordered specifically for an "alternative fuel / zero emissions test truck conversion. Truck was delivered directly to the dealer from the assembly line, and never went into service or driven down the road prior to removal. Mileage on engine is approximately 150 miles which was just the factory test drives. Dealer removed entire engine in tact, it includes ECM, engine harness, flywheel, turbo, everything... still fully sealed and secured to factory engine stand and crate. I had it plastic wrapped as shown in pictures to protect from dust and maintain new condition.
