The real HP/TQ numbers this is going to hurt!

From what I heard, the Ford engineered 6.7 is working out to be a good engine.

Not at all surprised at the results, how many V8 Diesels are in OTR trucks? Not many, usually straight 6 and 8 since they will produce more torque just by the fact they have more journals, one for each piston, where V8's have shared journals, and the V design takes away from the stroke where that torque comes from.

V8's, great for racing, but if you want a powerhouse for pulling a house down, you can't beat a straight 6. It's just too bad the Cummins in in a dodge. What the heck were they thinking putting a 5 foot bed on a dually?

there are a couple of other more major reasons for a I-6 vs V-8 in big trucks.

1) A I-6 is one of the few engines that has excellent primary and secondary mechanical engine balance. important for smooth operation and in large displacement engines.

2) an inline engine is much easier to work on and design intake and exhaust systems for.
3) OTR trucks don't really need to worry about engine length, unlike cars and light trucks where a I-6 is noticeably longer than a V-8.
