That’s going to be a popular swap engine.

What is this “pushrod” you speak of mr Ford?

It’s an iron block yuge engine , that thing is so heavy and large I can hardly think of any useful purpose for.

Wow... I really didn't see that one coming.

it’s probably smaller than a coyote.

iron isn’t as big a weight penalty as it used to be.  I’m not sure if this is a compacted-graphite iron (CGI) block but if it is you can get some impressively thin wall castings out of it.  It was good enough for the Ecoboost 1.0 3-banger and the 2.7 Ecoboost V6.

Pushrod= Perfectly adequate for a lower-revving truck engine.

kind of surprising since ford ditched the pushrod 20 years ago.    Grunty simple engines in trucks are a good thing.

I think GM has shown the entire industry two things:

1) pushrods are not a handicap if you know your application

2) larger displacement does not automatically mean poor fuel economy.

I just pulled a random dyno chart from google images to make a point. The vast majority of driving most users do is with the engine operating in the range between the two blue arrows:

lower-revving engines work fantastic here. for a truck application, it’s perfect (consider the fact that diesels usually redline below 4,000 rpm.) A peaky, high revving engine is great if you want hp/l, but it’ll be absolute shit when operating below its powerband.

plus, for every day driving (not just in trucks) that kind of “flat” torque curve is desirable.  a relatively flat torque curve means horsepower increases proportionally with engine RPM which gives better driveability.  Peaky engines are like “nothing, nothing, nothing, HERE’S ALL THE HORSEPOWERS NOW!”

Iron blocks take boost better than aluminum. Also having a forged crank helps tremendously

Because fleet maintenance.

The forge crank is a sign that this engine is gonna be boosted at some point... but from factory isn't it gonna be N/A?

I believe the Powerstroke uses the same material.

You say that, but what I hear is that this engine is gonna be boosted?

The press release says its cast iron.

It probably wont be boosted from the factory, but the aftermarket will be all over it.

I guess that if you were to mod it for CNG it would be a beast of an engine... but when you go up to such high displacements and heavy duty applications, shouldn’t you really be looking at an I 6?

jimz > Spanfeller is a twat 02/05/2019 at 10:14

1

No, not really. There’s nothing about an I6 that makes it inherently “better.” Heavy trucking settled on I6s for packaging reasons (engine can sit lower between the frame rails) and you can do a rebuild without removing the engine.

Based on the tech specs... Looks like Ford just brought back the Chevy 454!

They also used designs adapted for turbocharging like the piston rings and valves.

About 9 mins for that discussion

A 7.3L (445 CI) does not fit my ford knowledge of 400, 427, 428, 429, 460 and so on... Oh well. Should be great at swigging dino juice.

The class C RV market is still primarily built on big displacement gas engines, as is the rental box truck market. Ford will sell a bunch of cutaway chassis with this engine to RV manufactures and up f itt ers that build U-haul type trucks. If it has iron heads,  then it has potential for the marine market also.  I would expect most sales of this engine won’t be in consumer pickups.

4 bolt mains with cross bolts. Me gusta.

Wasn’t the IDI a 445?

Highlander-Datsuns are Forever > Jordan and the Slowrunner, Boomer Intensifies 02/05/2019 at 10:31

The only number arrangement I can think of is 454 but that’s a GM.

The 445 is the name of a ford tractor tho, was that intentional?

They’ve had two different 7.3L diesels, but not a 7.3L gas as far as I’m aware.

So the latest thing is bringing back big gassers with the same displacements as that company’s diesels? GM announced a 6.6 for it’s 4500+ trucks a little bit ago, now Ford with a 7.3L... time to bring back the Magnum 5.9L?

(yes i know the 7.3 p owers troke was killed long ago shut up )

444. The displacement stayed the same for what became the 1994 Powerstroke 7.3; Navistar’s name for the engine was the T444e.

Because diesel trucks are a false economy.
