Overall, the biggest structural difference between the 855 and N14 is the air-to-air cooling system changes but both engines are very similar. Cummins listened to it customers and designed a more powerful version of the 855 while maintaining a similar profile and bore/stroke architecture. The N14 engine is the follow up to the vastly popular Cummins 855 Big Cam which was produced 1976-1985. First designed in the late 1980s it was sent into full production in 1991. The engine features the best of engineering fundamentals mixed with one of the first electronic control system. No doubt, the N14 is part of “1,000,000 mile club”. These engines are the stuff dreams are made of if you’re an old school guy looking for reliability.

The Cummins N-14 is a great engine quite possibly the best Cummins engine ever produced. Cummins N14 Specs, History and Problems Cummins N14 Engine History
