I just read Ford deep sixed the 6.8 V10 and replaced it with 7.3 pushrod motor!

around here if you try to trade something in with a V10, they might give you a dollar allowance for it.

Got one in my F350 dually...
I need more than 200 characters for my "signature." I'd love to see that changed to 250!

Ya I've got a bus with the v10 in it. Its one of the biggest hunks of cast iron I've ever owned. Would not start all last winter.   I now have a buyer wanting it. I hope he takes it.

well, over the last 18 years, I've owned two PUs both with V10's and I had nothing but good service with them, except I learned to carry an extra coil/boot with me. I never even had the spark plug issues others have had, but, I was the second owner with each truck, so maybe those issues were resolved by the previous owner
I just bought a 2005 F250, with the 5.4. what a dog! has less power, and uses more gas! when I am pulling a trailer, its screaming.

Don't get me wrong, I like the V10, mileage is in the toilet BUT whether max loaded or empty, uphill or downhill or on the flats, city or highway, NOTHING seems to affect the fuel economy a whit. But put it in 4WD, and - cut almost in half. Half of single numbers is pretty poor mpg's! But it pulls like nothing else.

DITTO ON HAVING A SPARE COIL PACK!!! All 10 recently replaced, and after #10 cylinder (last one) was replaced, blew out the spark plug. Stranded at a little convenience store waiting for a tow in the worst whiteout snowstorm so far this winter. I went in for a cup of coffee and was surprised to see a friend of mine in there having lunch, he's a FedEx driver. I was even more surprised to see he was laughing, then asked me, "That YOU makin all that noise out there?" I said yes, but before I could say anything else he said, "I'm gonna say Ford Triton V10. In the past 10 years I've had 3 of them and every single one of them eventually blew the plug from number ten cylinder. Sound about right?"

Anyways, they had to flatbed it back to their shop, repaired it, with no guarantees. While waiting, I googled "Triton V10," holy shkamolie did I get an education! Instead of putting out a TSB about the problem, Ford shoulda done a recall.

The 6.8 V10 was a 5.4 V8 with two more cylinders... The 5.4 has been dropped and the F150 size trucks use the 5.0 , 3.5 turbo, or the 6.2 V8 motor ........... I would guess FORD phased out the remainder of the 5.4 "parts" .. (the 6.8 V10 ) ... and is going with a new motor.... and yes, I did read it will be a VERY SIMPLE design as compared to the later 5.4 with the variable cam timing, and a zillion parts..

Never did think v-10 in anything would work.

FORD sells more trucks than ANYONE... There is a reason for that... Every company has their problems and they work thru it... You just named  a Dodge problem... And I guess you never saw a Chebby rusted out after 5 years or their motor with no cam lobes ?

I think it’s purely a marketing ploy. I have had several customers call me and very excited that Ford is bringing back the 7.3 when I explain its gas they are very disappointed. If I remember they cut the V-10 and the 6.2 and replaced with 7.3. I am waiting for calls of someone putting diesel in a new 7.3 lol

The 6.2 is still being sold, at least in the 250/350 trucks. I had a different take on the 7.3 gas. With the bat rep the 7.3 diesel has, I think Ford would have been better served labeling the 7.3 gas 7.2, or 7.4.

FORD 7.3 L GAS V8--

Earlier this year, Ford introduced an all-new engine option for the revamped 2020 Super Duty family of trucks. During the 2019 Chicago Auto Show, the Blue Oval was not ready to disclose the output numbers for the unit but now we finally have them. And they are good.

The 7.3-liter V8 gasoline motor produces up to 430 horsepower (320 kilowatts) at 5,500 rpm and “best-in-class” torque of 475 pound-feet (644 Newton-meters) available at 4,000 rpm. Featuring a proved overhead-valve architecture, the new V8 also uses a variable-displacement oil pump, extra-large main bearings, forged steel crankshaft, and piston cooling jets for better temperature management under heavy load.

 
 
In fact, the new engine will be available in two power output versions. The less powerful one has 350 hp (261 kW) and 468 lb-ft (635 Nm) of torque and will be standard on F-450 chassis cab, F-550, the new F-600, F-650, and F-750 Medium Duty trucks, as well as the F-53 and F-59 stripped chassis models and the upgraded E-Series. The 450-hp variant, in turn, will be available in the F-250 and F-350 trucks, joining the already offered 6.2-liter V8 and 6.7-liter V8 diesel

I had three F450 dually service trucks with the V10 gasser.  They did miss... sometimes more than others.  I could HEAR the bad coil pack on a 'dead air' spot on the AM radio, but the dealership would frequently refuse to change anything 'because it's not throwing a trouble code'... when I could put my hand in front of the tailpipe and FEEL it missing. 

That being said, we had NO stranding engine failures of any of our 17 V10 Gas F450s.  We had one transmission failure, and plenty of plugs and coils, but no engine fails.    With our big service bodies, and ladders on racks on the roof, we averaged 5.6mpg across all those 17 trucks, and two million miles.  Our prior trucks were identical, but with the diesel series.  We averaged 6.3, with the exact same service bodies, ladders, etc., attached.

We went gas because the advantage of diesel was not commensurate with the added cost of operation AND... the engine failure downtime.

(yawn)  438ci, and 475 ft-lbs at 4000rpm...  it's nice that it develops all that torque, but what's it generating down at 2200? 2800?  3200?

My current F250 has the 6.4 V8, and it's horsepower ratings are something like 385hp, with 430ft-lbs at 3800.

Having the torque peak way up by redline makes for nice peak horsepower numbers, but it isn't worth crap at anything other than full-throttle accelleration.  When driving on the highway with a trailer, the engine is turning 2600rpm, having gobs of torque at 4k means you step on the pedal, wait a few seconds for the computer to figure out what gear it wants, and then you're out of RPM and shifting already.  Having the torque fat-and-flat makes for a much more effective platform.

I'm really baffled by the engineering concepts applied to powertrain... all the technology and complexity wasted.  I have a late '80's Chevy P30 bread van with a '76 Buick 455... it weighs exactly the same as my F250, but only has a 3-speed automatic, and same final drive ratio.  The bread truck is more responsive in traffic, holds it's speed, and climbs better than the newer challenger, and that can be attributed to putting down over 500ft-lbs from 2300 to 4200... with a quadrajet... and it gets better fuel economy than my service truck.

Apparently, the lessons learned long ago, were lost, and the prevailing solution is to 'throw technology at it'.

I hate to tell you there are still hundreds of thousands of 7.3s still running today. It was a very dependable engine. What do you drive? A Chevy with a Isuzu engine in it? While the truck rusts away?

Our F450's with the 7.3 Navistar... were the most reliable and most economically successful engines we ever had.  Not screaming powerhouses, but dependable as a steel-handled hammer.

Around here everyone praises the 7.3 Diesels and wishes they would build it again. I had one and it did what I wanted it to do. But I prefer the 6.0 diesel but I have a diesel shop and we only work on Ford diesels. I had a 6.4, and was not impressed. Long story there and to be honest I really don’t like to work on them. The 6.7s are doing good around here with a few issues but nothing like the 6.4 and 6.0s. I would put the 6.7 up with the 7.3 in terms of reliability. I have several customers with v-10s that I have worked on because they have diesels too. They seem to do a good job and my customers love them but there is a difference between gas and diesel in terms of towing.

You are right about the junk ford puts out. In the years I worked for a car dealership, we replaced more motors, trannys, in ford pickups than any other brand of truck. As our ford mechanic used to say. -- "If ford was a reputable company they would have recalled every v10, 5.4, and 6.0 motor and repaired/replaced them at fords expense". I owned 6 of them over the years I was in business. They did me no favors. Yes I have 1 now that my wife bought. As soon possible it will hit the road.

Tom this is not to dispute anything you wrote, but for perspective, there literally are more ford pickup still on the road than any other brand of truck, so it might have something to do with the fact that your shop worked on more of them? For myself, it has ALWAYS been Ford, family's always been Ford/Lincoln/Mercury, with a Dodge or two over the years, Jeeps always lol, and ONCE, a brother owned a Chebbie back in the 70s lol... but that's pretty much over - my next truck will probably be a GMC. But we'll see...

Can't get anybody around here to work on junk 7.3 diesel's! ---Nobody will touch them! Mine sits out back from the time temps go below 55 til in spring when it goes back up to 55 at nights, so it never gets any miles on it. --Its a F-350 dual wheel flatbed. --In winter I have to pull my dump trailer with the Explorer, not something I like doing but desperate times.

Dave,
I haven't seen the HP/Torque curves for this engine, so I'm talking in generalities. Usually, hi cube engines torque curves are reasonably flat. Sure Ford will tout the peak for marketing, but I suspect it would be respectable in the 2000 rpm area. HP on the other hand usually tracks with RPM real general terms, but in a truck pulling a load, its torque that rules the day....more or less.....see me hedging my bet!?? LOL Your comparison with the Buford isn't fair, the Ford has emissions to deal with as well as fuel mileage.
Your point of drivability is valid! I am seeing issues in drivability more and more in new vehicles. My company ride, 150 Transit is a royal pain to drive in traffic....constantly searching for a gear, and each time it does we lag in traffic, causing the according effect, lag, lag, lag...then I'm on the brakes! I usually do manual shifting in traffic

55 and under, I plug mine in for 1-2 hours.
Turn the key and it is running. Has over 215,000 miles and have just replaced normal wear parts.
F250 2001
7.3
2 wheel drive, long bed, ex cab, 6 speed
I also only change oil ever 10,000 t0 12,000 miles.
There are 3-4 shop around here, that's about all they work on.
Most of the motors they work on have 200,000+ miles.
