I doubt they will do anything for '23, it is blowing away the Ram and GM gassers. Until they up their game, I think Ford will keep it the same. I'd bet they have some extra HP and TQ ready when they need it.
I have heard rumors that they are dropping the 6.2, and coming out with a Baby Zilla that will be like a 6.8 based on the 7.3 block to have as the base motor.

Kinda like the black wheels, it costs no more to make those than the chrome/pol alum, but they charge what $4k more for the same wheel to be black?

If Ford dropped the 6.2 and streamlined with just the 7.3 I would think that would make life easier and more profitable for them. Sure there would be crying about doing away with the 6.2 but the 7.3 can do what the 6.2 can do but better and be on par with mileage of the 6.2 if that's a concern in a heavy duty truck platform. Only time will tell.

Are they truly derated in the larger trucks or are the hp/tq #s just taken at lower rpm points? In the 250/350 its hp@5500 and tq@4000. Found this in a Ford article.

I have not heard anything official, though at some point I suspect the 7.3L will get direct injection to meet emission standards. I have heard the 6.2L is on the way out and will likely be replaced by the lower output 'economy tune' 7.3L currently in the E series. I have a feeling the 6.8L 'Baby Godzilla' has been cancelled (if it ever really existed).

I'd guess the 7.3L will eventually get upgraded with dual Port/Direct Fuel Injection combo.
Maybe Ford is waiting for the rumored Cummins 6.7L gasser to see what hp / ft-lb they need to match/beat?
I'm thinking direct / port injection is worth ~ +25 hp plus a bit better mpg's

I don't have access to either one. So you're saying that max rpms are limited by engine controls on the bigger trucks? But mechanical components are the same...?
