What little specs I’ve seen suggests it will be a low rev push rod engine more suited for heavy duty use than high performance. But, everything is rumors now.
The old rumor was that the 6.2 OHC engine was going to be bumped up to a 7.0L, but that never happened.

We can wish, but I don't think it's likely. 2015 marked a definite shift with the lightweighting of the body and the elimination of the 6.2 L engine as an option. The current available engines already produce far more power than the chassis can handle, so they perceived benefit of a 7.3 L option doesn't seem that great in my opinion. By every objective measure the HO 3.5L completely embarrasses the 6.2L in the previous Raptor, would a 7.3 I'll be any different? It would be substantially heavier, and weight isn't fast.
To put simply: what with the 7.3 L do that the 3.5L HO EcoBoost doesn't already do, but using significantly less gas?

originally started this thread in the f150 raptor forum.
i thought it was interesting that the new silverados have 10 speed 6.2ls with 420/460 while the HD 6 speed 6.6 have 401/464.
looks like ford should make the 6.2l available in the 150s again and bump up the power ratings. the 5.0l 395/400 is very similiar to SD 6.2l 385/430. i still think they should make the 7.3 available in the raptor or bring back the 6.2 with better than 411/434
im keeping low expectations for the 7.3 but this thing should have big power numbers ~450-500/600

someday - I think you're a bit over optimistic in your ratings, but it would be nice if so. 600 ft-lb on a production gas motor meeting emmisions? I don't believe it to be likely.
I'll guess HP at 400 +/- 10, somewhere around 4800 rpm.
I'll guess TQ at 520 +/- 10, somewhere around 3400rpm.
Anxiously waiting the official numbers.

It would be nice, but I think that will be a bit of a stretch. Torque output is much more closely related to displacement than horsepower, as you can only shove so much air into those cylinders. Horsepower seems to vary significantly, because you can adjust the torque curve within the rpm band with cam profile and timing.
A lot of modern engines make an incredible amount of torque and horsepower for their size, but do so using the advantage of independent camshaft control for the intake and exhaust cams. Which is something that no Super Duty engine has ever had the benefit of.
We shall see, I hope I'm wrong!

the 3.5l rator has 450/510!
if the new powerstroke is gonna be over 1000 ft lbs and the 7.3 is supposed to be in the middle somewhere...i think 600 should be a start towing 20,000# trailers

The 3.5L Raptor isn't rated to survive towing those kinds of weights, either. Most semi trucks have less than 500 HP.

Hp and Tq are one thing, price is another. Give me 450hp and 500ft-lbs for $1,000 and I start shopping for a SD.
Economy numbers will also be interesting. Hopefully the 10-speed tranny can keep them near the 6.2.

No way is Ford going to offer the 6.2 in more F150s IMO. Be glad they offer a V8 at all!
I'm hoping for 425HP / 535TQ in the new 7.3. There should be a TON of potential regardless if initial rated output. I want to know what the heads flow!
