finally a return to large displacement gas V-8 engines over 7 liters. I have been waiting for this for a long time. I hated the demise of the 460 many years ago. An engine this size with todays technology would be a beast, and still get considerably better mpg then those big blocks of yesterday.

A Peanut Butter Sandwich • 1 week ago

Hey, 10.2 is pretty good MPG :P

karl yukon • 2 weeks ago

Interesting that Ford would go back to pushrod engines after abandoning them so completely for nearly 30 years. Maybe they finally realized that pushrod V8's have an advantage in reliability through simplicity. Plus they sure make a lot of room in the engine bay.

Fost04mach • 2 weeks ago

...where did you read pushrod?

Guenther Wilke • 2 weeks ago

Did I miss something? Where did anything say it was an OHC engine?30 years is a bit dramatic. More like just over 20.

Can't wait to see 0-60 numbers to know if it's the best product or just garbage 🤔

God & Guns 1776 • 1 week ago

Really? 0-60 numbers on 3/4 and 1 ton trucks is your metric?

435/505

OldFord • 1 week ago

I figure after this engine is out awhile companies like Roush will develop supercharger and/or turbo charger systems for it. I could only imagine the kind of power an engine this size would make with forced induction.

I am liking this. rumor of large displacement and pushrods.

Mobey Dick • 2 weeks ago

Just wondering, If Ford cast the current 6.2 block in Aluminum and used the "spraywire" technology they use in the Coyote for the Cylinder walls could they get 7.3 out of the current 6.2 platform. The 6.2 can be stroked to 427 so I believe it possible without changing the physical size or changing installation of the existing platform. That might be to easy for Ford!

Troverman • 2 weeks ago

Nope...the 6.2L is an OHC engine and the new 7.3L will be OHV. Completely different engine.

Sparky • 2 weeks ago

Both engine types you mentioned are OHV-do you perhaps mean a pushrod engine?

Troverman • 2 weeks ago

The 6.2L is single overhead cam, meaning there are two cams and the cams are above the valves. Overhead valve (OHV) means the valves are above the cam. OHV and pushrod are typically synonymous.

Sparky • 2 weeks ago

OHV means the valves are over the piston, rather than off to the side (like an old flat head - or most lawn mower engines).

Troverman • 2 weeks ago

In the context of all late model vehicles, OHV and pushrod are synonymous. It's true OHC engines are also OHV, which is why the OHC moniker is used.

Sparky • 2 weeks ago

As both OHC and pushrod engines are OHV, most will refer to a pushrod engines as a "pushrod" engine so as to avoid confusion. It just makes more sense.

Troverman • 2 weeks ago

All modern engines are OHV. So if you specify the engine is OHV, then to me that means it is not OHC, or you would have specified OHC. Wikipedia backs me up on this "Because OHC engines also have their valves in the head, they could also
be called OHV engines. However, the term “OHV” almost always refers to
engines with the valves in the head and the cam in the block. "
( https://en.wikipedia.org/wi.... But that's just semantics, you are right and I am right.

Guenther Wilke • 1 week ago

Not sure who there “most” people are, but in automotive engineering and manufacturing, it is referred to as simply OVH. This nomenclature, btw, is nothing new, but has been in use ever since flat head and OHV engines needed to be differentiated. Happy Friday.

Sparky • 1 week ago

Yes, I understand that long ago all OHV engines were pushrod engines and that some today persist (incorrectly) in using the term OHV to specify a pushrod engine, despite the fact that other OHV engine configurations have been in use for a very long time.

SC • 2 weeks ago

OHV based on what infomation...all indicators point to OHC.

Troverman • 2 weeks ago

The rumors are that the engine is OHV. Here's one link:
https://www.svtperformance....

And here's another:
http://fordauthority.com/20...

No indicators are pointing to OHC, despite Ford's history with this engine type.

FourLoko • 2 weeks ago

i dont buy ohv either. a 7.3 isnt much bigger than the 6.7 PS, minus a turbo in the valley. the heads for the 6.7 aren't small by any measure either since they are 4v/cylinder. squeezing ohc/dohc wouldnt be a stretch.

Troverman • 2 weeks ago

The 6.7L doesn't have any cams in the heads. It does have 4 valves per cylinder, and they are not operated with bridges like a Cummins or Duramax. Individual pushrods instead. The 6.2L is a large engine, as is the V10. An OHV design is much more compact and cheaper to build and maintain. It is also lighter, which helps payload and economy.

Troverman • 2 weeks ago

The other half of this confirmed rumor is that this engine is likely to be a pushrod, 16V engine, much like a GM engine. This will make this large engine fit comfortably into an engine bay and it should be simple to work on. I find it fascinating Ford chose to go large displacement in an age of downsizing.

Stuki Moi • 1 week ago

" I find it fascinating Ford chose to go large displacement in an age of downsizing."

A pretty good indication Ford doesn't expect a CAFE style regime for HD trucks.... Not sure how the bureaucracies plan to prevent a steady shift to HDs among daily drivers as a response to ever more stringent requirements for half tons, if this turns out to be correct.... Lower speed limits perhaps...

When operated on a more steady and demanding duty cycle, big engines can be as efficient as smaller ones. While being much easier to keep cool. And simpler and less maintenance intensive.

But they give designers fewer levers available, for gaming mpg tests conducted hauling air on flat ground.

Troverman • 1 week ago

It is interesting how the big companies have their own predictions for who is in power in Washington. I have no doubt this 7.3L will achieve better mpg than the 6.2L. Even if CAFE regs don't demand it, customers will. It probably won't be much better, but a little bit.

Mike Gaebelein • 2 weeks ago

It will be pushrod .. Cgi block and iron head.. Ten speed transmission.. Possibly to include dual fuel injection like on the 5.0 to help mpg... But once again this is to replace the 6.8 not the 6.2..6.2 will remain the base for fleets . But this will cost a few hundred in the f-250-350 .. Standard on motor homes and chassis cabs

Guenther Wilke • 2 weeks ago

Iron head??? Even the diesels have AL heads.

Mike Gaebelein • 2 weeks ago

This is per the uaw retiree chatter... Keep in mind this will be available on the 250-750 . Gas.. Propane and nat gas in various hp and tq

MrOzMan • 2 weeks ago

I’ll go 460/550 with my guess.

Mike Gaebelein • 1 week ago

I'm going 455/525 just a guess

BrazoriaCountyMan78 • 2 weeks ago

Now just fix the cheap garbage interior.

Troverman • 2 weeks ago

While the materials aren't always the best, the design and ergonomics are very good. Ford uses too much hard plastic inside, I agree (and I own a couple) but some of the materials are actually nice. King Ranch seats are very nice. Limited seats are even nicer, and so is the suede headliner. The wood trim on King Ranch, Platinum, and Limited is real. But obviously not everyone is so put off with the interior considering it's sales status.

What up doc? What part don't you understand lol?

Guest • 2 weeks ago
BrazoriaCountyMan78 • 2 weeks ago

7 words to the sentence that do make up one part. Maybe you have not been in an F150 or 250 but the plastics used are a step back from the previous F150 interior of which I was a happy owner of a 2014. The design is awful as well. So now with a new gas engine all there is left to do is hire some good truck interior designers and create an inerior worthy of the F150 name. That help? ;)

Jay • 2 weeks ago

Yes, thanks. Some people cant read minds through the internet, believe it or not.

karl yukon • 2 weeks ago

The plastics are hard and cheap sounding in many ares. Starting in 2015 with the F-150 the dash started warping and separating.

When I spend $40,000 I want to sit in nice interior, when driving every day.

Jay • 2 weeks ago

Its especially important that my dash is soft to the touch. I often caress my dash, sensually, and it just kills the mood when its hard plastic.

Jimmy Johns • 2 weeks ago

LOL. I was driving my F150 and thinking how many times I felt the dash. Maybe how many times I snuggled up to it or even rubbed my junk on it. I could care less if it is soft to the touch. I never touch it. Just wipe it clean and that's it .the same as my soft to the touch Fusion dash. I don't know how soft it is. I don't care. It's a dash. If it's dusty I clean it. That's it.

Moondog • 1 week ago

And guess which dash will hold up longer if that truck is used for work? Yep, the harder plastic.

Jimmy Johns • 1 week ago

Yup. My 13 year old work truck can still clean up as new. In the past few months I have spent $2800 on new "soft" door panels because they don't hold up.
