Likely specs: oversquare, 445 cubic inches, iron block, alloy heads, 2 valve pushrods, direct injection.

Alot of suggestions there its still based on the Boss engine, so i wonder why they would go with an OHV head. Any indication if theyre keeping the twin spark plugs or is that not necessary with direct injection?

This direction is not what i had hoped to see Ford go with their "next" V8. With their TTV6's getting smaller than the initial 3.5l, there was a gap opening up in their engine range for a small TTV8 very similar to what GM will put in the next Corvette. Its also commonplace now in German sports cars. This 7.3L might be a truck engine, but whatever Ford sticks in Mustang still gets kept alive by F series.

Is this a Propane (LPG) engine?

whitelion65 · 06-09-2018, 10:37 AM

Gas in the US means petrol.

Vesper Martini · 06-09-2018, 11:23 AM

I know but, they do run these large capacity Petrols on Propane over there.
see the F750 6.8L V10

Petrol engine, but it wouldn’t surprise me for it to be E85 compatible with CNG/Propane/LPG options.

This has some info on the Ford commercial vehicle flex fuel options.

Look at this stuff: Australia didn't really get how to promote its LPG industry

Reduced carbon footprint.

For many businesses, operating a fleet is the single largest contributor to their carbon footprint. When a business decides to reduce its carbon output, the fleet managers need to know how to identify which advanced fuel will make the biggest difference.

Reduced dependence on foreign oil.

Most of the world's oil reserves are concentrated in the Middle East. Since most advanced fuels are available in the U.S. from U.S. sources, switching to advanced fuels can limit how much money is transferred offshore to support our domestic energy demands.

Government incentives.

The U.S. Department of Energy allows you to search its database of federal and state laws and incentive programs related to advanced-fuel vehicles. Learn more

im not really following that thread???

in the pictures it has a OHC engine with 2 valves per cylinder and hydraulic lash caps on the valve tip but they keep talking about a pushrod engine?????????

i kinda hope its a OHC 2 valve with VCT with the bore spacing of 4.5 like in those pictures..... would be the mod motor ford have had from the start.

EDIT: my mistake those pictures are of the 6.2l

Yes, poorly presented article!

445ci
pushrod
It's 2018

MAGA!

I can't see how this V8 in any way relates to the Mustang. This is specific for Super Duty trucks to replace the ancient 6.8 V10.

There have been some rumors of a modern Boss 429 Mustang as well as using this engine in the F150 Raptor. I have my doubts, but we will see.

jpd80 · 06-09-2018, 07:46 PM

First test engines will be built at the end of the year, production of the 10R140 begins next year
with the combo debuting around August 2019.

That was kind of my point, this engine is useless for Mustang. If 5L F series sales get cannabalised by TTV6 sales, then why would Ford keep the 5L around? A 4L TTV8 in various tunes couldve replaced all of Fords current V8 range.

Well, of all things, yesterday I reserved a car for hire as I needed to take a business trip further up state.

A Hyundai Elantra. They are nice little cars and return measurably better real world driving fuel mileage than any other ICE powered car I have driven in that class. Peppy enough for what it needs to do too.

Anyhow, they were an hour late picking me up. Got to the facility and told all they have are E250 vans and 6 passenger F250 4x4s with the 6.2s.

I took an F250 at the same rate as the Elantra. Fair enough, but still pinged with the F250 fuel mileage.

I couldn't really test it's capabilities, yet is drove well. I liked it. It felt odd driving a Full Size 4x4 Pickup without 2 sticks coming out of the floor. Yep, dating myself.

Didn't use as much fuel as I anticipated. I'll get a better idea tomorrow when I fill the tank.

The 6.2 in the heavy vehicle gave me good impression.

A pushrod 445? Is this what happens when you put a furniture guy in charge of a car company?

At this point all we can do is wait and see.

Mostly for Medium Duty - F450 to F750.

Venomous1 · 07-09-2018, 06:10 PM

Limited Run Of F150 Super Raptors Would be cool but won't happen.

Ooh hire car...

big cube, two valve, pushrod donk ftw

LOl, no skidz (on camera) just these. Hope my neighbour doesn't mind being on AFF.

jakkes · 08-09-2018, 11:50 AM

indmar have been using that 6.2l for powering wake boats with a few hp/tq ratings even a supercharged version is available

Crazy Dazz · 08-09-2018, 03:09 PM

Just goes to show...
SUVs now covered by CAFE laws: "We must all play our part to combat carbon emissions"
Super Duty Truck not covered by CAFE laws: "7.5l V8 Hell Yeah!"

As for the configuration.
If you want a V engine that is cheap to build, cheap to maintain, will last forever, and the principle consideration is low down torque, then a single cam with pushrods is the way to go.

Although I also wonder if Americans will ever wake up and realise that diesel engine are not a pinko commie plot?

I understand what you are saying and agree that is how it is often executed, but I can say many of the things attributed to the ohv pushrod engine are not certainties. More a matter of execution.

I have had my fair share of 6.5L ohv pushrod V8 engine involvement that make max tq in the 8K+ rpm range, max hp in the 9.5K+ rpm range, shift in the 10K+ rpm range and cross in the 10.2K+ rpm range. A lot of work and engineering goes into those valve trains.

The SOHC with the rotated wedge/hemi combustion chamber configuration in the 6.2 and available upward displacement is a hell of a design to back away from.

I'll take a 445 with matching SOHC heads of similar configuration as the 6.2 any day. Not really interested in a GM look alike.

Speaking of the General, we can thank them for the diesel perception in the States from driving a fairly lethal nail in the diesel coffin back in the 80s when they tried to convert a very stout Olds 350 petrol block into a diesel block. Absolute disaster with long term effects.

Of course you can hot up a push-rod, but thta's not the issue here.
The target market is people who use these trucks for towing, often in "5th wheel" configuration. If your goal is massive low down torque, then a push rod will achieve that with ease, and do it cheaply and reliably.

And of course you could easily tune a OHC or even quad cam to do the same thing, but why bother? Especially with an engine that's going to be fundamentally huge to begin with.

jpd80 · 08-09-2018, 08:34 PM

Back when the 6.2 was first being developed under the "Hurricane" project name,
the Ford brass pushed hard for it to be a pushrod engine, they couldn't see the sense
in making it OHC. but what they didn't know was that the engineers were having massive
problems with Ford's version of cylinder deactivation. From Accounts, there were more than
a few spectacular failures. so it was decided to add some power and efficiency with a generous
OHC design that incorporated big valves and ports along with variable cam timing. The engine
was a compromise that never really lived up to its full potential and while it worked well in the
F250 and F350, ot failed the reliability test for medium Duty trucks, it just wasn't big enough
for hours of sustained loading that would come in the bigger commercial trucks.

Why do you believe an OHV will make massive low down torque?

The point is, the location of the camshaft(s) has little to nothing to do with the tq and power curves. Again, it goes back to how it is executed; primarily cylinder displacement vs cylinder head generosity and valve timing. Note: all the proper ancillaries must be capable of the application.

The SOHC inherently has a more stable valve train regardless of rpm. Why back away from it?

GTMOND · 09-09-2018, 10:10 AM

I find it hard to believe that it will be pushrod. Time will tell.
