Puzzled a bit by the 5.0 V8 Cummins offering. That engine seemed to pop up out of the blue. Alot of R&D and tooling goes into a new engine design and the market for the Titan is small, and might only get a little bigger. There has to be a wider market anticipated beyond Titan. But industrial/marine/commercial folks don't like v-block engines (at least little ones) as exhaust plumbing is a PITA and bulky and high parts count. From photos, it looks like a conventional exhaust layout, with manifolds on outside vs inside of vee. Puzzling they did not put the exhaust inside, makes truck fitup much easier.
Maybe they intend to shift this engine into HD trucks and other brands. That long 6.7 straight six won't fit in any modern truck unless it is designed for it (ram). Hard to say it really fits in there, either!! The 5.0 probably will fit in any pickup but the compacts.
Will be interesting to watch.
