Peterbilt’s long-length Model 387 tractor is now being offered with the Cummins N14 engine. The N14, with horsepower ratings from 350-525, will be available beginning May 1.
Peterbilt said the N14 engine strikes a desirable balance between power, fuel economy and dependability, with a reputation for long-life-to-overhaul and easy up-rating to increase resale value.
