1985 Mack Magnum Superliner , 91 E9 450 turned up to 500HP, about 400K on engine.all internals replaced last rebuild as well as pump, turbo, etc. 96 volvo cut off with tall bags, 18 speed trans , 3.90 rears. Truck was built a true Magnum but would need quite a bit of work to bring it back to all original, but great truck as is, Hill pulling machine, mechanically very good, just shows it"s age a little but can be cleaned up well I believe. These trucks are getting harder and harder to find.
