lol... Get rid of one of the most reliable engines ever built for a ford?
Id rather run an AMC smallblock and keep the AW4.
For 350 or less you could buy a used CD box (Like a 6al), update your injectors/fuel rail, new intake and exhaust.
Another 200 would get you a good cam that the ecu would still like.
That would easily give you a good bump, and still keep the torque down low where you want it.

what year is that f150 motor? you may find it actually doesn't even put out as much power as the inline 6. Our 6 cylinders beat out alot of V8's actually.

Most 302/5.0 Fords are in the same HP range as the 4.0 engine.
Even the 5.0HO in a Mustang was only rated 220HP just 45 more then you have stock.
IF your going this route, get a 5.0HO from a 88-92 Mustang.
Forged pistons, low tension rings, of course roller cam.
Then add a set of good aluminum heads and you can easily make 300+ HP from the stock short block.

Another big plus is the 302 is short and light. It's about 40lbs lighter than a 4.0 and shorter so it will keep the weight farther back which is huge in the mud! Add a set of Aluminum heads and you can take another 40lbs off that. Plus more room in the front of the engine bay and a more simple accessory setup makes it easier to work on and easier to delete heavy junk like the a/c compressor that never works anyway. So 100+ hp and 100lbs lighter for less than $2k sounds like a reasonable swap to me. And the sound of a lopey 302 in an XJ
Lastly, if reliability is your concern, I haven't found anything harder to break than a forged 302. We have beat and beat and beat FAST (500+rwhp blower, turbo, nitrous) stock short block 302s in Mustangs for years and they put up to some serious abuse. The block is weaker than the rotating assembly and can split down the lifter valley if it sees over 500rwhp for years but I think you're asking for a lot of other breakage if you have that in an XJ

Another thing to remember is regular 302 and Mustang HO cams have a different firing order, but it's as easy as switching the plug wires around.
Edit: Thought you meant $350 into the 302 sorry.

PS - you were never going to be able to get a complete 5.0 drivetrain and convert the XJ to accept it and make it run for $350.... not even close.
