just got this a couple days ago. they say they over rated the HP by 25 and TQ by 18.. offering 300 bucks to say sorry or some crap..

quote

430 HP...... but the base Godzilla crate engine costs $9,175,

end quote

$9175 divided by 430 HP = $21 per hp

You were shorted on your factory version of the 7.3 V8 by 25 HP

25 multiplied by $21= $525

Write Ford and counter-offer for
a free one month lease on a Ford Lightning pickup EV
since the news says dealerships are sending them back to Ford

Sounds like they're trying to avoid a class action lawsuit

But on the other hand at least they're offering something unlike some other Mfr's

I have a 2020 super duty with the 7.3.. Previous trucks were a 99 super duty with the v-10, bought new in march 98. Also a 2011 with the 6.2 bought used in 2014, All three crew cab long box. The 7.3 seems to be an awesome engine, although I have heard some grumbling of failed camshaft and lifters due to delaminating.. Gas mileage for all three about the same towing. The 7.3 is much better empty then the other two They had 3.73 rear axles, the 20 a 3.55) Being almost 60, I also have an everyday car, so this most likely will be my last new truck purchase as it is in the garage with only 18,000 on it.

They have to by lying, it was never "over rated" at 350hp, it was already de-tuned. Issue is they put this engine in fleet vehicles, fleet vehicles get driven by guys that dont care so they'd never unleash the full 430hp to those guys and apparently 350 was too much as well. If I had a motor home with the 7.3L I'd be looking for a tune to unlock as much as possible seeing as its not a fleet truck being beaten on by 47 different employees.

Thanks for posting.

After watching this video I would guess the root cause is improper camshaft lobe hardening
rather than lifter roller metallurgy
{edit: wrong guess}
but I bet Ford already knows and is so far being silent.
I suspect date of change on part numbers would give owners a clue.

More likely to be a peak RPM related failure
than peak Horsepower.

Chrysler had problems with its first roller lifters
and Deiter Zetsche had to delay the first year of the 5.7 Hemi due to camshaft bearings.

Retired Ford Engineer and racing motor guru Brian Wolfe relates what he suspects is happening with the hydraulic roller lifter in the Ford 7.3 V8 in the 1 hour 38 minute to 1 hour 44 minute segment of this long video interview:

Wolfe believes the roller wheel is “Brinelling” and the failure is not a camshaft problem, although the camshafts are ruined by the lifter.

He states that on a boosted racing 7.3 V8
he replaced the stock roller lifters with Johnson 2126 roller lifters

Ever since Ford announced its 7.3L “Godzilla” engine, the automotive aftermarket has been figuring out new ways to utilize the platform and improve upon its performance characteristics. Few engine shops have been more successful at that than Willis Performance Enterprises in Willis, MI, which specializes in small block Ford drag racing engines, and more recently, performance parts for the 7.3L Ford Godzilla engine.

That success is in huge part thanks to
Brian Wolfe, who operates Willis Performance Enterprises (WPE), and is the former director of global engine engineering at Ford Motor Company.
Brian’s background has allowed him to experiment with a variety of 7.3L Godzilla combinations from mildly modified to fully built and boosted.
