I believe the 14L Detroit is the Series 60 that was produced up to 2008 with the different DDEC models you hear and see discused here. It was also produced in the 12.7 L as well. The DD15 and DD13 are the two models of engines Detroit are building currently (15L , and 13L of displacement) . Its like how Cummins switched from the N-14 engine to the ISX they currently produce. The companies started completely from scratch to bring a completely new engine to the market.`

The difference is the engine family. The Detriot diesel corp. class 8 engine was usually a "series 60" starting back in the early 90's they were 11.1L and more commonly 12.7L and then there were different generations of refinement ie. ddec I,II, III, IV up to I believe 2003 where they switched over from 12.7 to 14L to meet BHP ratings due to EGR also I think they also switched to ddec V with was the last update in development, they carried that version of engine through 2008 where the "DD" engines came into play. The DD13 is 13L and the DD15 is a 15L and there is a DD16 also....Some useless trivia for you there was pre EGR 14L starting in 2000 they came in at 575BHP/1850TQ and 550BHP/1850TQ they are rare I own one factory installed, but I would advise against buying one because parts like Turbos and engine specific parts and VERY hard to get.
