IS IT TIME 5.7 TO GET DROPPED ???

Really? For trucks, the inline 6 cylinder provides the strongest block architecture, which is why all the semi's run 'em. Individual cylinder bearings, inherently balanced (as is the V8, of course). The limiting factor was how much material you could get in the power cylinder to keep 'em together.

I'd try a turbo inline 6. Wife's I4 turbo is a low rpm torque beast. I really like it, compared to the wheezy V6 NA we had prior.

Inline 6 engines have had inherent head weakness issues in some of the last generations of 4.0L. Diesel 6 cylinder heads are much stronger as they have to be, but that also mean much heavier. My concern with an inline 6 turbo is the head pressures mid-engine I.e. between cylinder 3 and 4, as they tend to be weaker here. That is of course unless someone designs the heads to basically have 4 head bolts per cylinder to assure clamping force and head warp, particularly if the go with an aluminum head.

The larger engines have individual cylinder heads, fyi. Cummins tried to cheap their way out of not designing a new head for the ISC engine, yet had to yield and do it post mortem due to all the head cracking and gasket leaking. Does not mean the I6 is not the strongest architecture. It means the designer cheaped out.

Last time I checked, Ram doesn't have pending ligation against them for ZF transmission in their vehicles like Ford does for the 10spd.
The ZF HP series is used by multiple manufacturers included BMW, Audi, Bentley Rolls Royce, to name a few.
I think your confusing more gears means it's better. Why Ford had to join with GM to develop the 10 spd was due in part to ZF telling Ford it's not worth the extra weight and complexity.

You have an excellent point. I didn't mean better in terms of reliability. I meant better in terms of the more closely spaced gearing allows the motor to stay closer to its power peak. In other words the 10 speed makes the most of the power available. This was most noticeable when driving a less powerful vehicle like the 2021 Ranger with the 10 speed auto. The 10 speed also has slightly smoother shifts, likely due to the more closely spaced gearing. I would certainly agree that is a very limited definition of "better".

So the ultimate answer is the old CVT?

No thanks!

The dealer told me Chrysler modified the 5.7 by directing a greater flow to the lifters for 2021. I was the dealers first 2021 to come into the service department.

How was this done?

I really hate to say this but I have been looking to get new truck and I have test drove few out there and our hemi IMO come near last only worse engine out there is that stupid GM 5.3 , I have test drove 6.2 from chevy 5.0 from ford 3.5 ford even 2.7 from ford I think is putting a good fight, definitely strong little fu@#er and gets great fuel milage .... our hemi is nice and smooth but is showing his age underpowered and love to drink gas.

So test drive an old Ford twin turbo and see what you think. Total Cost of Ownership is initial cost PLUS the cost of ongoing maintenance and repairs. What's the cost to replace two turbos? Why do you see so many Hemi trucks still on the road while the 5.3L Fords disappear fast? If you want to pick a new truck, start by test driving one of the brand's older trucks--if you can find them still on the road.

today on marketplace I saw a 13 or 14 f150 for sale for 5k Canadian. clicked on it for fun and you guessed it, blown turbos :party36:

a comparable year ram but in proper working order around here is about 15k

How many miles? Many engines used for towing hatched ~ 70k miles, I read on trade magazines in the 2000's.

I went back and looked for you, and converted to miles
161k miles!
prettt good for an ecoboost!

I was born in 86 but I clearly remember seeing cars in the 90s (from the 80s) that as my dad would say "couldn't get out of their own way".

I was born in 57. I remember and owned cars from the muscle car car era. The the epa came in, added pollution controls and unleaded gas. Wasn’t till the late nineties that power started coming back.

The only surprise is that Chrysler as a brand survives that long. They haven't had a hit since the 300 was new, and the minivan is the only thing that's kept them alive since. Dodge is the Joe Everyman Muscle brand, RAM is trucks doing truck stuff, Jeep is one of the biggest 'lifestyle' brands ever, and Chrysler is...quasi-luxury and minivans. They've been struggling to find a niche and successfully market to it since Plymouth was still a thing.

Since when is Stellantis a brand of Chrysler? I see that reversed farther down in the article, but sloppy writing like this leaves me suspect of the publication and author.

Anyway, it remains to be seen what is meant by "Chrysler Brand" going all electric, since the Ram Brand is still alive, as is Dodge. Chrysler is late enough to the party it looks like nothing more than a quick hit "me too" attempt, which usually proves a disaster.

You're reading it wrong. They aren't saying Stellantis is a brand of Chrysler, they are saying Chrysler is a division of Stellantis and is currently troubled.

Reported elsewhere, Chrysler has been given 8 years to prove it's worth or get the Plymouth treatment and fade into automotive history.

Right. Chrysler is the trouble Stellantis division. Chrysler is going to be the EV brand. Stellantis is not a brand, period.

These big bore engines are for trucks being trucks. To be able to haul loads when needed and not straining the engine until the heads blow off. You got alot of ""artificial"" HP in the V6's and electronic HP. Real HD HP has to come from big bore engines to survive years of HD use. If you want a V6 turbo small block engine, then go get a Dodge dakota or one of those ""MID SIZE"" pickups. If not,,,RAM it!!

Ah.......without mentioning the name. Got it - sloppy journalism in my book. Oh, well.

IS IT TIME 5.7 TO GET DROPPED ???

do you think CHRYSLER need to drop the 5.7 hemi

5.7 hemi is ok in ram1500

TIME FOR CHANGE !!!! need more power to keep up with competition
