The gas are great for fun factor, but when you work them hard, the diesel is what you want. I know a lot of guys just won't buy a diesel for whatever reason, so the big gas is probably a good idea. Ford sold the heck out of that big gutless V10, just because it sounded good on paper.
The anti-diesel world is growing, that is because of increased maintenance costs/ reduced reliability, high fuel costs, high up-front costs, new emissions regs. Fleets went to Ford and asked for a heavy duty engine that doesn’t have these because the diesel isn’t making sense anymore. This is what they responded with. The 6.8 V10 was 350 horsepower, the 7.3 is 430 horsepower and MUCH lighter being pushrod with a 10 speed. It will be nothing like the V10.... Lots of fans of this new engine in the Super Duty forums it’s got an excellent torque curve and is relatively detuned for reliability reasons. Sure they could raise compression and get 500 horsepower, but that makes a peaky torque curve and less longevity factor. As it stands you won’t find an HD gas engine in the market with a better torque curve:
