5.0 vs 3.5 - more reliable when driven hard?

[Samson16]

Now when JExpedition was replying to Samson’s claim that a hybrid V8 is far too long and JExpedition07 shows data a longer I-6 powertrain will be made,

3rd person! Very nice! What data did you provide regarding an I-6 hybrid? Maybe I missed it. I'm shooting fast today lol.

Why are you replying to me? This makes literally zero sense.

Oh I know! Pick me!

Why?

Because 780 is extremely bias. First he comes in the thread and says buying a V8 is an emotional and uneducated decision to insult the owners, then posts videos of 5.0 issues. Now when JExpedition was replying to Samson’s claim that a hybrid V8 is far too long and JExpedition07 shows data a longer I-6 powertrain will be made, 780 says I-6 are the best motors ever and much smoother than a silly V-formation engine. Thanks for coming to this Ted talk.

Nobody said it mattered, specifically my point.

I replied because you mentioned length. It was a legit question. I was really curious why length of the drivetrain matters. I really don't know so was looking for clarification. My mistake if I missed something. Honestly wasn't trying to start anything. Just having a discussion....

And I'm not biased one bit. Not sure how you got that impression. I posted 2.7 issues as well. Didn't bother posting 3.5 issues cause everyone already knows about phasers etc... My point being that there is no clear answer to best engine. I've stated multiple times, just buy what you like. FYI probably 90% of the 48 vehicles I've owned have been V8's.

But yes, I6's are noted for being smooth.

I've only owned three I6's. Two 4.0's in Jeeps and an XJ6.

EDIT: 4 - I6's. I forgot about the POS FJ80 I owned for like 6 months.

I think you may have confused Calson and I. I never said buying a V8 was an emotional / uneducated decision. That was Calson. My 13th gen was a 5.0....

Interesting how people ask about the "best" engine and then ignore the information about reliability and make an emotional decision to buy the V8. because they like the sound out the tailpipes.

What people do not realize is that more cylinders for a given displacement equals more pollution and that is why V6 engines have replaced the V-8 engine in most production vehicles.

It is also wrong to compare the Cummins engines that go into pickup trucks with the Cummins engines being used in big rigs. Cummins engines going into pickups are no more reliable than the Ford or GM diesel engines and all are subject to much greater wear on fuel injectors as a result of burning diesel fuel. Replacing injectors on a V-8 diesel is a $4,000 repair job.

The reliability is worse for the Ford V-8 engine and that is a matter of fact. That was the concern of the OP and nothing more. Reliability can be objectively determined by the repair history and costs incurred by owners.

That reality does not mirror preconceived notions seems to create cognitive dissonance for many people on the forum which shows how much of an emotional investment there is with regard to cars and trucks.

The V-8 may sound better in terms of the exhaust and this is by design. Automotive engineers work very hard to create a sound that will be appealing to buyers. There was a documentary on the next generation Ford Mustang where a lot of research and development went into the sound of the exhaust.

I do not see why someone making an emotional decision is a bad thing. People decide on a larger tire or particular color or chrome additions to make their truck appear "better".

33% more cylinders is 33% more moving parts (roughly) and thus increasing complexity / moving parts = additional failure points.

Wow...this thread is still going......

Well now I know you're not talking about me cause you said sword not pocket knife...

@ 28 yrs old: fanging a NA 1.7 boxer engine Alfa Romeo 33 QV around the bends of the Great Ocean Road, horn blaring at all the V8's to GET OUT OF THE WAY!!

@ 60 yrs old: can't wait to get my KR 5.0 and sedately cruise the Great Ocean Road with a GoPro, asking the passenger "do you hear a faint beeping noise? Seems to be coming from the rear somewheres?"

This should solve the debate + ? = ?

hindsight being 20/20 i probably would have ordered the 302 versus 301 that i got, but that was over 6 grand of options at the time i wasn't willing to spend

I have a 301a, 5.0 was the. Standard engine with 4x4 Scab, 8’
That 302a—6 grand for a bunch of crap I have no use for.
all I wanted in the cabin— cloth, console, 8”infotainment and a leather steering wheel.
underneith—locking rear, 36 gal tank, step boards and 18” wheels.
A/C, tilt, cruise and PW I would have ordered if not standard on virtually even the base models.

The more moving parts something has, then more stuff that can break.
So 2 extra rotating pistons, rods, bearings, 8 extra valves, extra cam lobes, you get the gists turbos are very reliable. Every diesel has them don’t they?
N/A 5.0 V8 all day

 

[fassford]

5.0 with a chain driven oil pump and timing.

3.5 while fast, bear in mind that the turbos generate the power and they will fail.

With good maintenance the turbos have been shown to last. All diesel trucks have turbos. And the tuning of the eco is insane. With stock everything but tune and intake mods on 33in all terrain and 4door I’m in the 11s if I have to change turbos at 100k it will be well worth it. Doin 0-60 in 3.5 in a XL and in the next moment towing 12k is unlike anything

This is a pretty childish pissing match, the only thing I’ll add is that there are way more reports of late model 5.0’s getting the engines replaced than in either EcoBoost variation.
