2014 engine compatible years?

my 14 5.7l ram 1500 stutters and shakes. Gives cylinder 5 misfire. With the sounds previously it was making and now this, I am betting on a lifter failure. 200k miles on it and has given me zero problems till now.

ANyways, I am trying to decide between buying 2 new cylinder heads ready to go, with a new camshaft and timing set or to swap whole motor out with a low mileage junkyard.

My questions are:

1) it is easier to pull the motor than it is to change out the cylinder heads and timing with new camshaft while the engine is in the truck?

2) what compatible engine would work with this year ram? I know i will need to swap out parts, but are the blocks the same for 2009 and up, or did something change with the 4th gen that requires I stick with these years?

3) The junkyard price on average around here is $2400 for a motor (plus Core) for a supposedly sub 30k mileage motor from about the same year. On contrast, I figure about $1k-$1.4k for new heads, timing, and camshaft with all gaskets. Engine has 200k on it, so replacing all the top end components still leaves a 200k bottom end. Which route to go?

4) A buddy of mine swears these newer motors are designed better than older ones, and says I could probably just pull the one head and replace the lifter and put a new camshaft in and be fine. Any thoughts on this?

The truck still cranks fine and wants to run. other than one engine code with that misfire, everything is fine.

What’s wrong with the heads?

honestly, I just assumed a cam and a lifter issue would cause a issue in the valves or something. I am mechanically capable of doing the work, but I am not expert in any of the gritty technical on motors. Especially the hemis. Im a old ford and toyota guy before now.

The heads will be fine, just get them rebuilt while they’re off. A failed lifter/cam won’t do any harm to the heads. The HEMI is a cam in block engine, not overhead cam like you’re probably thinking.

The easiest and cheapest thing would be to stick with the engine you got. Replace the cam and lifters (if that’s actually the problem) or rebuild the engine you have.

im finding the lifter kit with gaskets it 500. timing set with bottom stuff is 450. camshaft is around 400. not sure what the cost for rebuilding the heads would be. creeping up to 2000 pretty quick. Am i looking at the wrong parts lists? thanks for replies btw

It will add up quickly but at least if you rebuild the engine you have you know everything is in good shape. You may be able to find a cheap used engine, but it’s a used engine and you have no idea of it’s history or maintenance. You can go whichever route you choose but if it was me I’d rebuild/repair what I already have.

ok. i will study some on the steps to rebuild vs replaced with used. As always with everyone, ill be trying to round up the money for either route.

on the motor compatibility, am I having to specifically look for a 2013 and up block ?

As long as it’s a variable cam/MDS block it’ll be the same. I can’t recall what year was the first year of the variable cam timing though, it was before 2013 though.

Why not look into a reman engine,there's lots available and most have a warrenty.
