5.7 vs 6.4

[Redthies]

Hard pass on both trucks for me.

That’s great. Thanks for the valuable insight.

If you guys in the USA would stop buying all the export trucks, there might actually be a used HD market here for me to choose other trucks.

The next closest options for me are 15-18s with 40,000 less miles, but triple the money.

The 6.4 will get better milege,and will blow the 5.7 into the weeds as far as power goes. You're very gullible if you think MDS has anything to do with engine longevity. Sounds like you've made up your mind already,so why are you asking for our opinions

And your comprehension level seems low. Nowhere did I say MDS was a bad thing. I just was looking for confirmation the 6.4 has it. I have a Ram master tech and HD truck specialist in my circle, and he has stated a lot of the 5.7 issues stem from the lack of oiling and lifters “deflating” to deactivate their cylinder, which leads to premature cam wear on those cam lobes and lifters. At least that was my understanding of it. Are you a Ram master tech?

I am definitely leaning towards the 5.7 truck based on personal needs, but I like to make an informed decision, and that’s why I’m asking about the pros and cons of the 6.4 engine.

If MDS caused the issue, the wiped lobes and failed lifters would strongly correlate to the cylinders that shut down. Non-MDS lobes would be "safe" and not see the same failure, right? That's not the case. I'm not bothering to rehash this well trodden topic beyond that.

You're master tech has his head up where the sun don't shine,lol.The lifters get more oil when in mds mode,they use oil pressure to push the pins in on the sides of the lifters for mds mode,so you're boy doesn't really comprehend how the mds system works does he. The only oil the cam lobes get are from the oil flung off the crankshaft,same way pretty well every V8 that's been manufactured on this side of pond has been oiled since the dawn of the V8.

I’ll check out the videos. I was paraphrasing my understanding of how they worked, and his engine side is Cummins, not Hemi. Mine too. I’ve owned dozens of Cummins, and zero Hemis. Hence my asking you for the info.

So let’s sum up, shall we? 6.4 is greater than 5.7, but not necessarily if 5.7 is the latest updated version and has 100,000 less miles on it. Can we agree on that blanket statement?

Any truck I buy will have a purchase inspection done at the nearest Ram dealer, and have a carfax pulled. At this point I am leaning towards the black 5.7 mainly due to payload being +/- 600lbs more, and the fresher engine and owner maintenance. The blue 6.4 is a one owner truck, and the guy is a serious Mopar guy. He has a 70s ‘Cuda as well as a 70s Power Wagon in his garage. I don’t know why the deferred maintenance on his rear locker, but I’ll certainly ask if I end up going to see it.

Doesn’t mean he has quality vehicles. Good luck.

Who doesn’t??








I was just looking around and just found another ‘14. Very clean, but 148,000 miles on it and he wants $35,000. Crazy…

 

[White six four]

Is that another power wagon? Just a suggestion but why not look for a regular 2500? Cheaper and with the money saved you can modify the truck how you want.

You should ask who you're you asking for advice from. Rick is a master builder and racer, dude. Arrogance as a new member for anything leads to shunning. MDS works by opening a solenoid valve that OILS the lifter bores, pressing in a spring loaded clip in the lifter body to collapse the lifter inner piston. Daimler-Benz invented it when they owned Chrysler.

It's bad enough to come here and spout info as a newb, doubly bad when you don't know what you're talking about and could have googled it 1st. Show some respect or leave.

What you're telling us you'll be using the truck for,why are you looking at Power Wagons,a 1500 would easily do what you want.
You could probably pick up a newer lower milege 1500 for a little more money then the power wagons you're looking at.
You're looking at trucks that are a dozen or more years old,if you take that same money and start looking at 1500's,you're probably looking at trucks less then 7 years old.A quick search finds lots of 1500's in the $30,000 range that are 10 years newer with alot less miles

Wow. You are a real treat. I’ve said NOTHING arrogant, dude. And I have no idea who “Rick” is. Has he posted in this thread? I haven’t seen anyone with that name post yet.

I also didn’t come here and “spout” info. If I knew what I was talking about, I wouldn’t be asking for first hand experience, would I?

Show me where I have been disrespectful.


If anyone is being disrespectful, it’s you.

I’ve zero interest in 1500s. I stated it would see moderate towing and hauling, so I don’t really need a 3500 either, but I live in an area with a lot of steep rocky terrain, and a lot of snow. I am off-road literally every day. I’ve owned 3 Rubicons and more than a dozen Land Cruisers with lockers. I use my trucks offroad. I don’t want a diesel this time around, but I do want a full-size pickup that is capable of getting me where my locked Land Cruiser can, but with a pickup bed.

I didn’t bother with mentioning all the uses that the PW is great for, as we all know its capabilities. I focused my questions on relative benefits and detriments of the two engine options.

If I didn’t have the offroad uses in mind, I would definitely look at the standard 2500 or 3500, but almost every single one in my price range (I am looking at them as well just in case a gem pops up) is diesel powered.

While I appreciate that some of you don’t like the two trucks I linked as potential options, I have multiple other rigs, including a 2025 Land Cruiser, so the PW doesn’t have to be perfect. I’m going to take it places where it will definitely NOT be perfect when I come home. Paint and body are a low priority for me on this truck. I do 98% of my own wrenching, so mileage doesn’t scare me as much as some people. Obviously, starting with something better is nice, but $10,000 vs $30,000 to get a prettier truck with 30,000 less miles seems foolish given my use case. I can replace a lot of parts with that $20,000.



I’m not saying all this to argue with advice you guys are offering. I’m just clarifying things so you understand why I’m ok with trucks that some of you are crapping on with the “Hard Pass” comments. I’m not offended by your opinions, and I don’t understand why a couple of you seem to think I’m being an ass. I currently sit as a chapter vice president on Cumminsforum, so I’m certainly not known to be arrogant or disrespectful. Quite the opposite in fact.

 

[Redthies]

You earned a block smart ass.

What the heck is your issue with me? I’ve done nothing to deserve your comments.

 

[Wild one]

A full sized pick-up that'll go where a locked LC will go,you're dreaming Dude.
Good luck though,i wish you all the best with what ever you end up buying.

Power wise my stock 18’ PW feels like my old 14’ 1500 with the 5.7 that was tuned.
