Main bearings showed no measurable wear with 1,000,000 miles of hard
pulling. After this inspection, all of the original parts were
reinstalled except for two cylinder kits. These cylinder kits
were selected at random and kept for trade show use. This
engine is still working hard for Pepsi Cola in Gulfport, MS |

was poured back into the engine and the truck went back to work. |
