" If you have an XJ that is 96 or later, you are in luck as you can keep your PCM. The downside of the more modern XJ though is that the GM computer won't talk to the Jeep instrument cluster, so you'll need to build your own from aftermarket gauges."
"A lift of two inches or more is recommended to allow clearance between the oil pan, exhaust system, and front axle."
"You can swap any of the LS based motors into a jeep you want, from the 4.8 liter truck motor, to the 6.2 liter Corvette powerplant. However, you will need to do some mixing and matching of intakes, oil pans and accessory drives to make it all fit in the Jeep."
"The Jeep radiator is inadequate for the LS engine. Also remove the A/C condenser, transmission cooler and just about everything up including the grill and front crossmember. Unfortunately, the low hood height and small grill makes it hard to find a factory LS radiator that fits, so Novak made one. Otherwise, find any generic LS aluminum radiator that is small enough to fix in the engine bay."
"If you are using the Novak motor mounts, it is recommended you order their headers as well. If you are creating your own mounts, or using universal weld in units, you may be able to get away the using factory F-body (Camaro/Firebird) manifolds."
"... try to get a matched motor/transmission out of a parts car. Then just worry about adapting your transfer case to it."
"You can and even should, reuse the XJ fuel pump if it is in good working condition and originally had EFI. This will make it easier to replace in the future and it holds plenty more PSI than what the LS calls upon. The throttle linkage cable can be connected, unless your LS is a later model with throttle by wire ..."
"A neat project, if you don't want to order up a box of aftermarket gauges, is to adapt the instrument panel from a GM truck, Camaro, or Corvette. "

Jeep XJ Engine Swap Options: https://overlandterrain.com/jeep-xj-engine-swap-options/
"If you're looking for a cheap diesel engine to put in your Jeep Xj, the Mercedes-Benz OM617 is one of your best options. It consists of a 3.0 liter, turbocharged inline-five cylinder, which produces 120 horsepower and 180 pound-feet of torque. "
"If you're looking for some decent power, you could consider the 4.8 Liter LS engine. They can be found in many SUVs from the 90s and will produce around 300 horsepower and 305 pound-feet of torque. You'll also need to install a harness to make the engine work."
"If you're looking for something a little different and abstract, consider the 5.0 liter V8 engine, offered by Ford. It's found in older mustangs and will produce 225 horsepower and 300 pound-feet of torque as standard, but this can be upgraded and tuned pretty easily. "
