I've thought about them - I have used MC flares is in the past and loved the quality (though the powdercoat does leave a little to be desired). I really like the thought of using aluminum though something simple like the KBD flares are also quite appealing. I picked up a cheap set of...

For sake of emissions compliance (now and in the future), and not wanting to deal with fuel vapor smells in the garage, I'm retaining the EVAP for sure. This is actually quite an easy process as the JSS Swap Kit integrates the EVAP control into their kit.

While I'm waiting for parts to come on Black Friday sales, I'm wrapping up some odds and ends that I can. On the interior, I removed the ignition park-interlock (the one that prevents you from removing your key when the transmission shifter isn't in "P"). Since my 8HP70 won't have a need for it...

Just like what I found during my TJ Hemi swap stuff, there's a lot of information to absorb and digest, much of which is scattered in bits and pieces across the web... At least when I was doing my TJ swap, there were some forum pages and readable materials that made sense and had good info. Now...

What size tires are you running? I'm running some 285's on my daughter's Islander. I was wanting these ST1 springs but lots of reports said that they gave a lot more lift than what yours is showing. I checked the PN's on my OEM springs themselves and they appear to be the HD springs used in...

Pilot Bushing & Bearing Removal You may or may not have to deal with this, but thought I'd include some tips for what apparently is a common issue getting these bushings and bearings out of Gen III Hemis. Many of the 345 Hemi Crate engines come "fully dressed" - full of oil, exhaust...

I've decided to keep the bulk of the Hemi swap info in a separate forum thread: https://wranglerjkforum.net/threads/jku-hemi-swap-reference-guide-swap-info.32731/ I'll still post a lot of progress info here, but technical details, part #s, links, resources, etc. will be there for easy future...

Final Wrap-Up Drivability TBD What I'd do differently TBD Thanks to vendors/sources TBD Total Cost We've all seen posts on forums and Facebook where someone claims that their best friend's, neighbor's, daughter's boyfriend's dad did a Hemi/LS for $2500 and a case of Natty Ice. These same...

FEAD & Accessories (PS, AC, Alternator, Intake) Mopar refers to the accessories at the front of the engine as the "Front End Accessory Drive" (FEAD). You will often see this in Mopar materials, especially on stuff that isn't vehicle specific and is intended for use on their crate engines...

T-Case & Transmission Prep (8HP70) T-Case Selection If you intend to run the 8-speed, you will need a t-case from either a 2007-11 Jeep JK with Auto Trans or a 2007-18 Jeep JK with Manual Trans. If you have a 2012-2018 JK with Auto Trans, you'll simply need to source a used t-case from a...

Engine Prep (5.7 Hemi) Refresh items You have a few options when it comes to sourcing an engine. Depending on where you live, you can easily source a take-out engine, and if you look around, likely a complete take-out engine + trans (ideally from a Ram 1500 with an 8HP70 if you're looking to go...
