Ford Super Duty 7.3 GAS motor

[newdude]

I can see a bigger than 6.0 engine being used by GM.  If the 6.0 can be made more competitive, why hasn't it?  Just because it can pull its rated weights, doesn't mean it can do it as fast or as good as a larger, more powerful engine could.  Yes, the 6.0 is a great engine and all, but look at the power the 6.2 puts out in the 1500.  Big block torque. 

 

HD needs a new powerplant to compete and to comply with any future emissions standards.  Same with the 4500/5000 coming.  Heck, maybe that's where we will see it debut first.  Remember, Ram and Ford offer gas in theirs, GM should as well.  There are those that do buy them.

Lots of companies like capable heavy duty trucks and do not want the b.s. associated with the modern junk diesels they build.  I work in industry and you see lots of V10 Ford 450s with decks and pickers on them... diddly for diesels because fleets don't want to be bothered with the unreliable emission stuff.  These trucks idle constantly... try that with a modern diesel that isn't deleted... These aren't trucks bought by Joe Blow to go get groceries in or haul his holiday trailer twice a year that are being looked at.  The demand for a large gas is there with how useless the epa has made modern diesels to a commercial client and hence why Ford is doing it.

Why would Ford need to develop a big displacement engine, don't they already own part of International? I want to remember they already have some big gas engines...

I don't buy the "contractors want gad engines" argument. For every gasser contractor truck around here, there are probably five diesels (in the same chassis). My lowly 6.0l 2500hd is a major minority around here...

You aren't everywhere and it doesn't really matter if you personally don't buy the argument.  If there was no demand they wouldn't be building one now would they... so tell Ford they are wasting their time then lol.  It will probably sell just as many or more than the 6.7 once it gets rolling.   And yeah... International has a larger gas engine... It's called the 6.8 liter V10.  They run it on natural gas in school buses too lol.

The 'direct injection' version of the 8.0L is gonna be a screamer....

 

 

Maybe they'll bring back the handshaker transmission as well.

Bingo

 

Nothing but gas F-450-550's and gas Ram 4500-5500's around here.

 

Diesel is done in this series of trucks, customers are not buying them.

 

Ford kicked themselves in the butt as you can no longer get a crew cab gas F-450-550, guessing the 7.3 will bring that option back.

 

I managed a huge fleet of trucks and the company was not happy when their old GM 4500-5500's started rotting out and dieing, they even looked into has them refurbished but couldn't find a source to do it. All the trucks were 8100/Allison and were great trucks.

 

The International's that replaced them were junk.

 

If you want to see the future look to company's like UPS to see what their fleets are doing as they spend millions to figure out what is the most cost effective,very few diesels left in their fleets.

The Dodge 4500 and 5500 aren't really that spectacular. Everyone got excited when they first released, then the specifications were unimpressive...I think they thought they would target the local contractor market.

Ford has that market cornered with the 450/550 offerings...

It would take quite a bit to break into that market with Ford leading it and Dodge having a few years in the arena.

Ford has pushed themselves out of the market as they did away with the gas motor in the crew cab F-450-550's.

 

Lots of 6.4 gas 4500-5500 Rams out there getting it done, they are dirt cheap and money is what fleet managers see...

Ford just redesigned the Heads for their 6.7L diesel to get what 5-10HP?  Seriously?  GM would not do that unless something is wrong?  Actually, the Heads on the L5P were of utmost concern to GM and the design and MFG was ridiculous in time and money from what I gather....GM is also not grenade the L5P'S check out the 6.7L forums....engines going off like every other day........  

 

Point being FERD has more engine choices than I can keep count?  Reason is well they pretty much suck and always have in my opinion...GM will just use the 6.2L and have everything the FERD 7.3L so more wasted time and money for FERD....which is starting to show much more these days as to confusion and lack of focus for future from Management....... 

GM will not use the 6.2 as it does not pass the heavy duty cycle testing...

 

Ford isn't hurting, 700 million into a new engine development is pretty serious, I think they will figure it out...

Hmm, most of the UPS trucks around here are going back to diesel...they were all gas a few years ago, them and the FedEx trucks are diesels now.

There are very few gasser HDs around here, most are diesels as I stated before...

Big fleets want big gassers with torque... simple as that.  Good on Ford for actually listening to the customer.  Diesel is dead... It just doesn't know it yet.

[grizzlyltz]

I agree
Oil field trucks in my area all seem to be going gas

1. hmmm....this is all interesting how quick they have gone back and forth in the fleet business....I guess location/climate plays a big part too.  I also do remember 2010,2011 might be off a year one way or the other most of the Diesels were having problems with emissions from idling..... I forgot many fleet trucks Idle all day and never really pull anything

That is correct.  I was going to work for UPS but my hearing went out on me.  While I was there, they were getting in new trucks all the time, all were Diesels.  They have a mixed bag of trucks out there, some Diesels, some Gas, but most were Diesels.  Right now they are phasing out the late 90s 7.3L Powerstroke powered models.  They generally keep the trucks now for 20-25 years max then they all get scrapped.

Let's straighten out a few things:  First, International (Navistar) has NOTHING to do with Ford anymore.  Some IC (a Navistar company) school buses use a PSI 8.8L gasoline/propane V-8.  This 'Big Block' is a modernized and larger version of the old 8.1L.  This 8.8L may start showing up in some International trucks next year.  Bluebird school buses offer a propane Ford 6.8L V-10, but no International bus or truck ever came with the Ford V-10.

 

Now, about this new Ford gasoline V-8:  It is supposed to replace the 6.8L V-10, will be around 7.3L, and should debut in the 2020 model year (late 2019).  Beyond that not much is known.

 

So, what about G.M.?  Well, that's an interesting question.  Yes, Chevy will start selling medium duty 4500/5500 trucks again next year.  The trucks are the result of a joint venture with Navistar (and International dealers will get their own version of the truck to sell).  These trucks will debut with the L5P Duramax/Allison drivetrain.  Word is that these trucks will eventually offer a gasoline/propane/CNG V-8 engine.  Rumor is that it will be a new large displacement V-8, not the current L96 6.0L.  No idea if this rumored engine is a Big Block resurrection or based on the LS.

 

So, it's safe to say that GM will need a larger gas V-8 in the near future, just like Ford does.
