Doing simple displacement difference using 6.2 numbers as baseline, the 7.3 would be 453 hp / 506 lb-ft
Unfortunately it's not linear. Lots of old school engine building articles out there attempting to show the difference in displacement vs. horsepower/torque and most of the time the horsepower increase was minimal yet the torque increased quite a bit.
These two engines are significantly different so it's going to be interesting to see the final results. For me, that's still a few years away as we need to see the real-world figures for fuel mileage, both unloaded and towing. My 6.2 has more than enough power for daily driving and is certainly adequate for towing our 9K travel trailer.

The GM 6.2L is a little different. First, it’s aluminum, it has variable valve timing and a higher 11.5 :1 compression.
I have the same 6.2L Gen 5 marine version in our boat built by Volvo Penta. It’s the perfect engine for both. Light, powerful, efficient...but probably not designed for long term heavy duty truck use.
I think longevity is the main goal with the 7.3, along with simplicity.

Agree, it's not linear. If it's only going to be rated in the low 400s, one could argue why did Ford bother developing and tooling a completely new engine.

My money is on 450/500 +/- 10.
I think your right. Those numbers would beat the other 2 companies gas motors pretty handily while not terribly taking away a significant amount of diesel buyers.

Go another direction...7.3 and the new GM 6.6...same basic architecture minus direct injection (which I'm sure will come eventually)...using the 6.6 numbers gets the 7.3 to 443/513.
I'm thinking 425/490 is the floor for 2020. More power will come later.
I'm starting to get impatient I need some numbers.
No need for patience. Nothing to shake the earth. I think we know where it will end up, given a tad more or less..which really won’t make a decision making or killing difference.
Whether it’s +-20 or 30 more horses or torque...it’s still half of the diesel upgrade.
I’m good with where the diesel numbers are, as crazy as that sounds. I can’t keep back tires on my truck now, it’s that slow peel when you take off. And feels like I’m going to rip the tongue off the trailer too.

around 500 ft lbs and 440-450 hp would be enough for Ford to claim highest HP and TQ for now. as far as the Diesel goes it will get a minor bump in power most likely to put it above the ram's torque so probably like 1025 FT lbs and probably like 460-470 HP.
Agree, it's not linear. If it's only going to be rated in the low 400s, one could argue why did Ford bother developing and tooling a completely new engine.
Because Ford needed a new efficient, reliable, and easier-to-repair engine for the medium duty trucks. Ford didn't really need a new pickup engine, the 6.2 is adequate and the diesel is the majority of sales by a long shot. From what I read, the 6.2 will still be the standard offering and the 7.3 will be optional which will make the 7.3 volume even lower for the SD's.
