Can a newer model Hemi go into a 2011 truck?

So in January I had a lifter failure which took out the cam of my 2011 Ram 2500 with the 5.7 Hemi. I ordered a remanufactured engine from an outfit in Portland and after months of waiting, I received the engine. When ordering it, I specified the truck was a non-MDS truck. They ended up putting a cam/lifter package for an MDS model in the engine so I had to bring the engine back and have them put the right parts in it. To be clear, this was their fault, not mine. I ordered the right configuration.

After installing the engine, the engine starting ticking after about 5 minutes of break in, correlating with a cylinder 4 misfire. Now, when I turn the truck on and it's cool, everything sounds and runs fine. After the oil warms up and hits about 110 degrees, bam! Misfire and ticking which sounds like it's coming from the valve train close to C4. I have checked the spark and fuel delivery. Everything is fine. There is nothing I could have done in my part of assembling what I had to assemble that would have caused this. I used the proper break in oil.

Now the company that I bought the engine from is saying that their warranty only covers up to $850 in fixing the engine. They want me to pull the engine whicnh I don't have time for. If I have it pulled, bring it to them to fix, and have it re-installed, it will run about $2200 of shop cost which I will be on the hook for after the manufacturer covers their $850.

I have a hard time accepting the fact that I have a brand new (rebuilt) engine that I paid $2500 for and now I have to cover the cost of repairing the brand new, defective product.

So if I have to pull the engine, I will be pushing to just return the damn thing and get a refund. If I do, I will be ordering a reman'd engine from a different outfit. So my question is this;

The 5.7 Hemi is a bit of a pig in a full size truck. It is probably unlikely, but is it possible to order a rebuilt, larger displacement engine like the 6.4 and installing it and have little to no issues with it? Will it use the same engine mounts? Will I have to manipulate the tune much on the ECU? Will it bolt up to the tranny? and so on...

Probably too much work to make it function for what I am willing to invest, but I have heard that the later model engines are less prone to lifter failures which is what took out my old engine. TIA for any advice.

Ok 2011 had mds and variable valve timing unless it’s a 2500 truck like yours is. You can get an mds and vvt engine from 2011-current in a 5.7, 6.4, or even the 6.2 hellcat engine and install it into the truck. The main difference will be the flywheel will need to be your current not the nag1 setup style. The tune will need an adjustment for the bigger engines 6.2-6.4. If you get a complete say used engine all you basically would need to do is swap the injectors from the bigger engine into your truck fuel rail and I take setup if it’s different. All the other sensors are the same. The mds can be left alone if you were to get an mds engine it wil simply not work or you can swap the lifters out under the heads and swap the actuators for block off plugs. Regardless any hemi 5.7-6.4 2011+ will work

Good to know. Thank you. Yeah mine is a 2500 so it's got no MDS which is a good thing from what I hear. The most likely scenario is that the valve in C4 is not priming. If that is the case, the company that built the engine will send my local shop the parts and have them replace the lifters and of course, the head gasket, coolant, blah blah. The company that built it will pay them $850 and I will be on the hook for the roughly 200 dollars that will remain from the bill.

If the engine has to come out, I will likely have to yard it out myself to save the money. It will suck because if I cannot get them to just refund me the purchase price, I will be stuck with an engine that is now repaired and that "warranty" will be of no use because they have now spent the entire $850 that they contribute through their warranty. Based on that, I see little value in having them fix it at all. It would take less time for me to pull that head and replace the lifters myself.

Lifter! Not valve. The lifters not priming. My bad.

What I'm understanding is the first engine was MDS and you returned it to remove the MDS. They sent you the same engine back. First I would guess that engine still has the MDS cam installed which is different than a NON-MDS cam. Even so it shouldn't tick. I would ask to return it for refund.. but of course that is unlikely to happen.. I would want to know the oil pressure when the tick starts. Possibly using a higher viscosity would help the faulty lifter.. unfortunately I would need to do the repairs myself so that I'd know it's been repaired. If they are willing to send you the $850 for repairs I would accept that and do the repairs myself.

Don't forget the tone wheel change in 2013.

I thought I read the two versions of the later 58 tooth wheel was interchangeable, but there were some possible issues using the earlier 58 tooth sensor and recommended using the newer one. I have no personal experience using the 58 tooth reluctor wheel.

Ok did a little more digging. The tooth width changed in 2013. It is still a 58 tooth setup but the spacing changed. Not sure if it won’t work or will work but 2009-2012 are the same for sure.

Did read somewhere that red seal and green seal crank sensors need to be used with there respective reluctors.

What state are you in? While I get that the engine reman company supposedly had a written policy with an $850 warranty limit. BUT- many state consumer laws don’t allow such if the product is delivered in a defective or “not as advertised” condition.
