that's great information bob, thanks for the help - I'll let you know how it goes! Just in case anyone else out there is wondering how this is done, Bob says:
"Essentially what you're going to use from the RAM is the long block. You'll need to swap the following from your Jeep engine to the RAM donor:
- Intake manifold
- Exhaust manifolds
- Oil pan
- Drip tray under the oil filter
- Oil filler neck
- Motor mounts
To ensure everything fits correctly I'd suggest you use the fuel rail from the Jeep rather than the one from the RAM. There may be slight differences due to the difference in the intake manifold.
Also, the power steering pump may be different as well. Look at the pics in my original thread showing the bosses in the left cylinder head; you may have to tap three of them to get the power steering reservoir to bolt to the head. It is just a 10 minute job to tap those bosses.
Get a new oil pan gasket/windage tray - don't reuse the gasket from your Jeep. The gasket/tray deforms when you take off the oil pan and so you shouldn't reuse it. Thought: Look at your oil pan and if it has a fair amount of rust bubbles you may want to consider ordering a new one from the dealer. They aren't that much - and again, the pan for the truck is different than the Jeep so you can't use it. The Liberty pan has to clear the crossmember and the drain hole on the truck is on the side vs the rear for the Jeep.
Get a set of intake and exhaust manifold gaskets.
The Jeep's harness will clip back up to the the RAM engine no problem. The EGR will be the same also.
The ****** and engine will go back together just fine - the RAM's ****** bolt pattern is the same as the Jeep's. You should use the flex plate off the Jeep's engine though; there are differences in the torque converters used in the Jeeps and trucks so just use your plate.
The swap I did involved an engine from a different generation (different computers, timing gears, etc) and doing the same as I mentioned above along with the timing gear swaps, the engine fired right up. It has been running like a top for 12,000 miles so yours should go very smoothly too. Again, you're essentially swapping long blocks keeping the intake, exhaust and oil pan from your engine."
Also, here's Bob's overview on what he did:
