Ford 7.3L Gas Engine

[goeduck]

That post doesn't even begin to say what was said in post 202 by Aaron. Not even close. Figured that's what would be referenced.

They both talked about puking engines and dash/idiot lights so I figured that must have been it. :confused3:

Hopefully Aaron can show us the post he was referring to?

If people get their feelings hurt over an issue with a motor they like, then they may as well walk. Every single motor at one time or another had some type of issue.

Agree. Some moreso than others.

So you are saying that a modern pickup should be expected overheat and puke coolant, atf, throw codes turn on idiot lights, etc from going 50 miles 60-80MPH?

I am saying that no stock pickup that is in good condition which was made in the last 10 years by any major truck brand should have a problem with making a 50-100 mile drive at 60-80MPH (or a 50 mile drive down dirt roads at 30-60MPH) when placed in "drive" and driven, and if it does, there is something wrong with it.

The two we have get driven at the governed speed, a little over 100 MPH, quite often and it痴 not uncommon to get on the Interstate and run at the governor for 20-30 miles, at night. Then, or before that, driving at wide open throttle with heavy brake applications, between turns.

I don稚 think they would have issues with normal driving. My post was in relation to driving them near, or at their limit, which is relevant as heavy towing in the heavy duty pickup market is a lot harder than driving the vehicle by itself in normal driving. As I said, I don稚 think the 2.7L EB, in current form, is going to survive in an HD application. They have better engine choices.

There is NO credible evidence that the 2.7 eco has the isssues you describe. Just the opinion of someone who has a bad uplifter/dealer. There are MANY satisfied 2.7 owners on TBN that I would rather take the opinion of.

Many people almost never use 努ide open throttle and will only be there for a few moments, when they do. The vast majority of drivers drive less in a year than our vehicles put on in three months. Rural LE patrol vehicles have about the worst life of any vehicle. A lot of idle time surrounded on both sides by full capability driving mixed with normal driving.

I知 not even saying I wouldn稚 own a vehicle with a 2.7L EB. I never said they were a bad engine. There痴 no way I would recommend it for heavy duty or severe use applications. It痴 made for daily driving with very occasional towing. Ford has better towing engine choices, which is why I don稚 see it ever going in an F-250, or above.

I want to apologize to the op. I am responsible for derailing your thread about the 7.3 to the 2.7*. Back to the 7.3-is this motor available in Ford’s heavy half ton (8 lugs), or does Ford not make that truck anymore?

 

[nikerret]

I haven’t seen a true heavy half in a long time, from any manufacturer. The 7.3L is only available in the F-250 and up.

ETA: I don’t think there’s really a reason to have a heavy half, anymore. They are all so much more capable than trucks from those days. Today’s half tons do more than the 3/4 ton of 15 years ago and with less problems.

The last one I saw iirc was a 2011 with the 3.5eb. I wondered if they still made them*

I went back and reread posts looking for the scenario you describe. I didn't find it. Maybe you can guide me to it? Thanks.

I was referring to nikerret's experience, but apparently I misread their post.

I’d like to read that post as well. A lot of us live on gravel roads, it’s hard on vehicles but not the cooling system. I don’t know how you drive 80 miles an hour on a gravel road anyway. 60, yes. Still, A police chase on a gravel road would be pretty self limiting and shouldn’t tax the cooling system of any vehicle. The radiator and cooling system are in front of the dust, and it doesn’t accumulate like mud where it would cake a radiator or anything like that that.

Ford makes a Heavy Duty Payload Package for the half ton. It has limited options, for example no Lariat ot King Ranch. I think the payload may approach 2500 lbs.

80 on gravel isn稚 unheard of or even uncommon. The last deer I hit was at 80 MPH, on a gravel road, in a pursuit. I was at full throttle, able to lift just before impact. The speed limit on most gravel is 55 MPH, here. Some of our roads are good enough 65 isn稚 a big deal. Others are so rough no one drives over 20.

In a pursuit, your cooling system is ahead of your dust, but not the dust of the person you are pursuing. Depending on the wind speed, direction, and moisture content if the roadway, the dust kicked up can be an inconvenience or end the pursuit. Add another patrol vehicle, or two, in front of you, you?*e getting multiple vehicles dust-not good on any vehicle system. The only way to not drive in their dust is to be right behind them, close enough the dust is still gaining altitude, not higher than your front bumper. Not great at high speeds, especially, in areas you don稚 know really well. The County is almost 900 square miles, no one knows all of it good enough to drive blind. The other option is to fall back, but that puts you right in the worst of their dust or so far back you aren稚 doing much.

Here?s a picture of the front if my PI Utility (Explorer). I had only been in the pursuit a couple if miles before the runner went through a field. I was driving around, to head him off when four deer stepped out, in front of me. Grill guards are important. The grill guard stopped the deer from causing airbag deployment, allowing me the opportunity to keep full control. It also pushed the deer forward, instead if it riding the hood into our faces. The deer landed around 150 feet from where I got stopped, which was quite a ways from the impact site.

Our local dealer just delivered his first Ford 7.3 to a guy that had a 8.1L BB Chevy for years so it will be a good comparison to the last of the breed from the bow tie group. For me personally, I would spend every dime I had to buy one of these 7.3 gassers IF I could get a 6 speed manual behind it.

^^I'd love to get one with a manual too.

Good luck. I had a hard time finding any manual in this truck category. Even the semis are moving to automatics.

Very true - but you have to make sure they are equipped for what you intend to do with them. When I was truck shopping 3 years ago the local Dodge dealer had 3 1500 models in stock. Payload sticker on each one was right about 900 lbs...they sure had a nice ride! But if I were to load my quad in the back and my camping gear - I would have been over the truck's payload.

Door sticker on my stock 2016 F150 supercab (no Max Towing package, no Max Payload package) is 1,937 lbs - a thousand pounds more than the Dodge! I need a truck that can haul a load more than I need a soft ride.

The 7.3 vs the old 6.2 on the dyno.........see the charts

Godzilla vs Dyno! This is How Much Power & Torque the 22 Ford Super Duty Tremor Produces! - YouTube

Wonder why they didn't compare the 7.3 to the 6.6. I think the numbers are much closer.

Because the 6.2 is the base engine in the Super Duty line of trucks. The 7.3 is an upgrade and the 6.7 is an even bigger upgrade. The diesel is $10,495 more than the base engine while the 7.3 is a $1,700 option

Ford doesnt offer a 6.6

I believe he's referring to the new GM 6.6 gas engine that's just been introduced. Would be interested to see how it compares to the new Ford 7.3.

I'm sure that test is coming with them loaded up with a run on the Ike Gauntlet. Also, test them for MPG too.

Nearly all medium duty trucks are automatics too.

 

[TSO]

Yeah I think they said they'd release the full video right around Jan 21st...

I currently have the 6.2 with the 6-speed and 4.30 rear end in my 2014 f250. It's actually a pretty solid combo and I usually tow up to 15K. No everyone, it's not a diesel..... I watched that dyno vid comparing the 6.2 to the 7.3, I think it showcases that Ford did a great job with torque Management on both trucks, as the torque curve on the 6.2 is pretty solid as well, and even appears to be more linear than the 7.3. I'm exciting to see how this thing really tows though and even though I might wait one or two years for them to work the bugs out, I think this might be my next truck!

Earlier in this thread I expressed my feeling that a pushrod engine was going backwards in design. I didn't know much of anything about the 6.2 offering. The 5.0 Coyote engine has been pretty reliable in both the mustang and truck configuration.

A while back I saw a F250 with a 6.2 for cheap and the dealer said it had a knocking noise in the engine. Doing some research online I found numerous complaints of 6.2 gassers with engine failures and noises so I decided not to go down a repair path. Seems like the same issues Ford had with the 6.0 diesel engine. It's hard to understand how Ford has remained the top selling truck with their recent history of engine problems.

I hope this 7.3 gasser turns out to be a change in the tide for Ford. I am a Ford fan but seeing how much a truck costs these days a bad reputation of engine problems will eventually catch up to them.

GM has seemed to keep the pushrod design up and running although it hasn't always been without problems. I bought a used 2003 Z06 Corvette some years back and the engine in those were famous for breaking valve springs and crashing pistons in or around 30K miles. I went ahead and replaced the springs on mine just for piece of mind but I didn't keep the car but a year. The vehicle had several problems a flagship model should not have had with driveline and electrical issues. At 43000 miles the pilot bearing went out and required a clutch job. I found a deal on a new torque tube in a box so I ordered and replaced that when I pulled the transaxle to do the clutch. The driveshaft components in those also had a reputation for being weak and expensive to repair. I lived in fear of what wold tear up next. That and keeping the car clean living on a dirt road was more stress than I could justify for a pleasure vehicle.
