Ford Says Its New 7.3-Liter V8 Can Fit In The F-150, Mustang

[smurfslayer]

That’s a really good video about one guy’s ownership experience. TLDW:

this guy had an ’18 with sporadic engine cut out, turned out he had a free spinning cam shaft; the phasers wouldn’t lock when they disassembled. he had some other minor issues before this, all issues were fixed and the owner traded on another ’18 Rap.

He said he’d buy it again.

I’m glad this guy said this because he pointed out, rather publicly Ford’s rather shortsighted “zero inventory” strategy. This guy waited 7 weeks to get his truck back, had to complain to C/S, got a loaner and a month car payment.

To me, this is not only bad customer service, it’s a serious monetary problem waiting to happen. If even the slightest issue causes a 2 week delay in getting parts, all a customer has to do is suffer 2 warranty visits in the factory warranty period to become lemon law eligible. Some states have shorter periods but my point is that Ford is not doing anyone any favors by keeping practically zero parts inventory. This is not going to work for the Navigator crowd. I don’t think their black label customers are going to be as forgiving as F150 owning peasants.

Which illustrates the whole cam phaser mythology is not as significant as some would have you believe, or they wouldn’t be powering the Navigator with ecoboost.

That video was so well done. Owner was honest and STILL bought another raptor because it really is in a class of its own. My 2018 SCREW is hands down my favorite vehicle I’ve ever owned. I think the idea of a gigantic V8 is great in the nostalgic sense but with the weight savings of the eco boost and the power output it’s hard to make an argument for the heavier iron block.

Has anyone seen the data from the other 3.5 ecoboost products? They reporting the same cam phaser failures, oil pan cracks, low oil, and low oil pressure? Look across the F150/expedition/navigator since they are using the gen2 ecoboost.

Has anyone compared sasquatch77 aliases post counts before being banned? I’m just wondering if the different aliases are actually more reliable than previous user names.

2 years and mine has been perfect.

I guess time will tell.

damn, it has been two years now. Weird, I've still not gotten used to actually owning a Raptor as opposed to just wanting one.

The 7.3 might fit, but everything I've watched and read suggests its more of a diesel alternative than anything. Pushrod engines are typically lower revving and prioritize low end torque over HP. Then there's the weight. It's huge, made of iron and has thicker sidewalls. Doesn't sound like something made for a "baja truck"

Cause Ford could never make an aluminum block version of a iron block design, right?

Both the 4.6L and 5.4L started off as weak nut iron block engines. Both eventaully ended up with aluminum block variants that were stronger than the original iron blocks. The aluminum block supercharged 5.4L topped out at 662 HP.

Ford is an OEM. They can do anything they want. There are no limits when you can make your own parts.

Spacewise, the 7.3L will fit anywhere a 4.6, 5.4 or 6.2 V8 fit. All of Ford's current V8s are huge with the OHC setup. The 7.3L will be shorter and narrower, and have a lower center of gravity.

I also disagree with your cam in block makes no high end power and can't rev comment. I mean- LSX. It doesn't need to rev very high either to make power with those huge cylinders.

Go look on F150forum the 2018 5.0 is having more issues than the ecoboost.

The location of the camshaft does not determine torque vs. horsepower or low revs vs. high revs.

The new 7.3 is extremely compact for its displacement. It's actually smaller than the 6.2 and probably lighter, too.

I'm not saying they're going to put it in the F-150 or the Mustang; they have given no indication that they will. But they definitely could.

I didn't say anything about location of the camshaft, I said pushrods. And yes, pushrods does have a correlation to high vs low revs as there's an increase likelihood of valve float with pushrods. And lower revving engines typically favor torque over hp. SO there's a correlation there too.

I only heard of one issue that is widespread- some ticking noise they get after letting off the throttle. What other issues do the 2018 5.0 engines have?

If we were talking about the engine that lives in your imagination instead of the one that was recently introduced, you may have actually had a point.
