Engine swap questions

Hey guys I'm planning on swapping my 4cyl out of my 98 Tj. I have a spare ax15 tranny I was going to swap in with a 4.0 from a previous jeep. But I decided I want to either swap a 6cyl stroker motor, or a v8. My question is which do you think is a better option? And if I decide to go v8, which will bolt up to my ax15? Or what v8 is easiest to swap. Not looking for any 500 horse power beast, just a simple fuel injected swap. Any info is appreciated, thanks!

98 is a great year to do it in. Hotwireharness makes a great harness but it will cost a lot. I'm averaging 19 highway 15 city with my 5.9 and 35s.

That's what I'd be running, 35s and probably sticking with dana 44s with 4:10s

Anyone running a stroker? Really thinking about swapping one of them in because there's not as much to modify. Or is there? If I can get my hands on one for a decent price.

Anyone give me some info on what I need to swap an already built 4.6l stroker into my 4cyl Tj? I also do have a donar parts yj with full 4.0 drivetrain and harness. Think I'm stuck between an i6 stroker and the 5.2 or 5.9 swap. HELP! Decisions decisions...

My buddy did a stroker and he averages 9 mpg I did the 5.9l and average 19-22 depending on how much foot I lay in it lol also a stroker is a lot more machine work still have to cut off and make new motor mounts still going to have to find a pcm. I vote for the v8 I love mine its reliable unlike strokers.
