I have a classic Mack B77 series for sale. I was told that according to the VIN number that it was One of 113 built with the super charger Cummins, known as the Iron Lung Cummins. But it does not have the original engine in it. Someone put in a small cam guessing 335 Cummins with turbo. It has a 13 speed transmission, Hendrickson"s pad suspension, or a Mack version of the Hendrickson. It is double framed, it has Mack rear-ends. It has been converted to 11R 24.5 tires fronts are virgins at 80 % rears are re caps at 70-80% with some weather checking.Runs and Drives, we have used it to haul our dozer and track hoe. For more info please contact me at 970-653-4279.
