There are PLENTY of shops out there doing Wrangler V8 swaps & have been for decades, there’s also no shortage of kits from cheap to all the bells & whistles to get it done in your home garage too should you feel
Inclined.
An LS1 & a Jeep Wrangler are like PB&J (yeah yeah I know mopar dodge etc but the LS crate motors are what has been going into wranglers for years)
If you want a serious off-roader that you can put away wet & dirty & worry bout @ a later time- modded jeep, if you want a “do anything” vehicle that has great resale, is relatively fast on & off road, has tons of room/practicality, & is more than capable in most offroad situations get the Raptor.
A V8 swapped Jeep is pretty awesome tho- and while the wrangler 392 is cool, doesn’t come w/ a stickshift does it? ;-)
