Get a used engine out of a Dodge pickup. Save a bunch of bucks for other mods.

Or have a machine shop do the short block and re-use whatever they can. Then bolt on Iron Ram heads yourself.

Don't Dodge truck 5.9s use a different cam compared to the ZJ 5.9? Not a big difference in performance though..

I say stroke it! Around 1500$ for the stroker kit + machining. 408 sounds pretty good

I just ran all the numbers for rebuilding a 5.2 which shares a lot of parts and was up to about 1300 in parts and machining. I had 2 different machine shops tell me that the heads are almost always cracked so I was opting for new heads at 330 each delivered. An overhaul kit with pistons was about 450 and machine work another 250.
Then you always have a lot of incidentals like oil, filters, antifreeze, belts, spark plugs, hoses, etc that can easily be another 100-200.

probably be cheaper/easier to buy a new/reman'd long block and bolt your old parts to it

As much as it's an oft-repeated thing, I have never seen any evidence that the Jeep 5.9 cam was different than the Dodge 5.9. The parts manuals for each engine have identical #s for the cam, and it would be pretty pathetic if Jeep upgraded both the cam and computer requiring premium gas and still only managed such a slight power increase over the Dodge engines.

No, as far as I'm concerned only the computer and its more aggressive timing was different. FWIW, the early 5.2 has a slightly hotter cam than the one the 5.9 got.

That sounds about right. Machining and parts cost me about $2000 when I built my 5.9, although things tend to be a bit more expensive in Canada. I agree the heads are likely junk.
