Why not just fix the engine you have? If it was me, that’s what I’d do, instead of installing a used engine when you don’t know the history of its maintenance or how it was treated.

The one in the pic has 186,000 miles the new one has 115,000

Even then, for all you know it’s been a rough 115,000 miles. It could suffer the same fate.

The amount of work spent swapping motors is gonna be just involved as replacing a couple headgaskets.

The one that's in it has 186,000 and the used has 115,000. So if I rebuild what I have, it still has 186,000 miles along with the tranz . The engine I'm getti g comes with the trans and transfer case for 1,500 bucks already pulled.

Ok well that wasn’t in your original post. It’s still a gamble with used components but at that price it’s not a bad deal.

Yes could be, but I would have 2 of each to put one motor together. One already out and another in. I can work on the one before removing the old? Let's just say I take the time to remove the heads. It's possible the heads are warped or the block is cracked. If that's the case. I have a second motor to pull from. how much are new heads?

Im thinking at 75,000 miles the same fate could be worth it.

Should be ok as long as the engine is from 99-03 starting in 04 they changed from a 16 tooth reluctor ring to a 32 which would give you issues unless you swapped it over.

Ok, the Durango I'm getting it out of is a 2000.
