Jamaican Bulldog Posted May 26, 2017 Share Posted May 26, 2017 (edited) In the peak of Mack's day such as when the revolutionary Maxidyne engines and powertrains were very common because of the their torque and efficiency, were there any cases of operators of other makes swapping out their Cummins, Cats, or Detroits etc for a Mack powertrain?
