7.3 to lose 40 LB FT of TQ and 10 HP for 2027

[VB!]

Chevy just dropped a 48X/50x 6.6

As I have followed all of this and can't seem to find anything definitive I wonder if this is all smoke and mirrors marketing, a giant April 1st joke in late Summer, sabotage, or???

If the day after GM confirms the new 6.6 numbers for 2027, Ford announces new numbers with an over air update that beats GM I would not be surprised. Call it the Fish Carb Update.

You guys are grasping at straws… Chevrolet’s press release is claiming best in class power and product managers don’t do that without verifying the competition. I know because I am a product manager, but in a different industry.

Not really. They have done crap like this for years. It wouldn't surprise me eather.

So the Gen 6 6.6l has only been announced for the 1500s. I don’t believe we know that the 2500+ will get the Gen 6. If it is a fact (I could have missed it) we don’t know the heavy duty power number. The 481/501 is on premium which would be an odd thing for a base model white 2500.

That being said, GM did put up some impressive numbers and I would happily run premium if I had a gasser. (I did on all my previous gassers as I had custom tunes.)

Since we’ve wandered into break in territory, any tips for a 1k planned drive from the dealership to the house?

I’ll be taking back roads for the first few hours maybe but the highway is coming. 1k miles is a lot to cover in 2.5 days.

7.3 to lose 40 LB FT of TQ and 10 HP for 2027

Had a little conversation with ChatGPT and landed on this: Ford eliminated the 6.8L entirely for 2027 and made the 7.3L the sole gasoline engine. That means Ford was simultaneously: eliminating one gasoline engine family, making the 7.3L universal across the lineup, modifying the 7.3L to...

Are we supposed to run 93 in the 7.3? I have been running 87 as it’s a basic truck.

I've been running 87 for three years with no problems. Here's a thread you might like:

93 or 87?

Is it worth running 93 in my 7.3 gasser? A Ford "mechanic" mentioned that you can run 87 fine, but it will retard the timing. I know 93 used to contain more cleaner than 87, but that was years ago, not sure if it is still true. Truth or hooey?

The 7.3 Godzilla was designed as a work engine rather than a performance (high rpm) engine, it was meant to run 87.

Gotta a link for that comment?

As for the improved oiling at the lifter bores and other tidbitz, I had asked Google AI a question:

I asked:

"My F350 Godzilla Tremor Package Super Duty was built April, 2025. I'd like to know if the engine idle oil pressure software was "correct" and if that truck's engine may have received better valvetrain hardware [proper heat treat of the roller lifters]"

G.AI - For a 2025 F-350 Super Duty Tremor built in April 2025, your truck sits right on the borderline of Ford’s rolling transitions for the 7.3L Godzilla engine. Here is exactly how your specific build date lines up regarding the software and physical hardware updates: [1]

1. The Idle Oil Pressure Software: Likely "Correct"

Because your truck was manufactured in April 2025, the PCM software from the factory should already include the updated oil pressure calibration. [1, 2]

The technical service bulletin and PCM calibration updates targeting low idle oil pressure were rolled out in mid-to-late 2024. Any engines moving down the assembly line by the spring of 2025 were flashed with the newer software parameters to prevent the variable-displacement oil pump from dropping down to that dangerously low 8–10 psi threshold at hot idle. [2, 3, 4, 5, 6]

How to verify:

To be 100% certain, you can ask a Ford dealer service department to pull up your VIN and verify if there are any outstanding Customer Satisfaction Programs (CSPs) or PCM calibration updates pending for your truck. [5, 7]


The Internal Valvetrain Hardware: A Transition Phase

Your April 2025 build means you missed out on the full, top-to-bottom physical engine redesign, which was officially finalized for the 2026 model year production (vehicles built late in 2025 and into 2026). [8, 9]
The absolute "bulletproof" hardware package includes: [9, 10]

* Redesigned hydraulic lifters with tighter tolerances and anti-bleed-down properties.
* Modified lifter oil galleries in the engine block to guarantee a steady, continuous top-end oil supply.
* A revised camshaft with smoother lobe ramp profiles to reduce friction.


The Good News for Your 2025: Even though you do not have the completely overhauled 2026 block casting or revised oil galleries, Ford implemented rolling quality control changes to the assembly line starting early in the 2025 model year production. Your engine does not suffer from the bad run of poorly heat-treated lifters that plagued the early 2020–2022 models. [1, 2, 8, 11]

The Bottom Line for a Tremor Owner

As a Tremor owner, your truck has a standard Super Duty pickup calibration (430 hp / 485 lb-ft), not the severely detuned, commercial chassis-cab calibration (330–350 hp) found in box trucks or ambulances. [11, 12, 13, 14]

The vast majority of catastrophic lifter delamination failures occurred on those commercial fleet vehicles because they sit and idle for thousands of hours under low oil pressure. With your April 2025 build having the corrected software and standard pickup duty cycle, your risk of a valvetrain failure is incredibly low. [1, 2, 4, 7, 11]

Howdy! Welcome to the FT.c

My opinion here is keep your truck at 55 or under for the first few hundred miles, but vary the speed if you can. I did this at the beginning of an almost-300-mile trip from Moab to Cedar City, UT after picking up my new truck that had 5 miles on it. I got almost 18 MPG, too! Hahaha.

But not since.

First morning of ownership, with now +/- 25 miles on it, just before climbing onto I-70 for the trip west from Moab.

So, yeah, the 55 is to keep the two differentials' ring and pinion cool.

As for engine RPM, switch off (using the +/- toggle on your shifter while in Drive) the upper two or three gears (10, 9 and maybe 8th) and vary your engine speed between 1500 - 2500 RPM with general cruise RPM and whatever mile per hour later on at 1900-2100 revs. You may continue to use the shift lever's +/- toggle to upshift and downshift when you want. Remember, too, these transmissions offer a Manual mode, where YOU do the upshifting/downshifting using the toggle. I'll do this in Tow/Haul mode, too.

After 500 miles you may increase your highway cruise to 65-70 and contintue to vary your engine RPM.

Have fun! You're going to LOVE that truck!

91 according to the sticker on my filler door.

I haven't watched this one, yet, but the title is kinda click-baity.

Just took ownership of a 2026 7.3L, but I also have a 2002 F250 with the ever-so-powerful 5.4L. It's lifted and has heavy ass, 35" Nitta Trail Grapplers. Talk about the bottom of the power standards. 🫪

 

[Velvet Elvis]

Now to see of ford drops the real specs on the 27. I cant find the power specs on there web sight now. Or maybe I just dont know where to look.lol

I've been hoping this is another 2011 power stroke style troll job. Whet they under report, wait fir Chevy, and then buddy slam them with the real tune.


Honestly, i was expecting a 7.3HO.

Instead.. we get what we got. For now.
