The video was fun to watch and interesting for sure. But lets face it, apples to oranges in most cases. OK I get it, the new engine is replacing the V-10. Its about time but it does not seem like the ball got moved forward at all. With exception of "faster off the line" I am not sure what the 7.3 does better. As we have learned, its not more fuel efficient. It won't be matched to a different transmission. Seems like its a wash.
The chassis upgrades seem more to the point of moving things forward.
Can't speak to the step van portion of the comparison
