I am looking to move to Colorado, most likely the Denver area. I am looking to do and engine swap before I move, most likely it will be a DIY project. I have 2008 jk, so I looked at swapping a 2008 Jeep grand Cherokee or Commander drive line and then use an AEV swap kit. From what I have read its better to use a 2009 Hemi that is a VVT, but the cost is quite a bit more. The other idea was to do an LS swap from Motech, which I like a lot better, but I emailed Robbie and he said Denver is hard to past. Has any one done any ls or Hemi swaps in Colorado and passed Denver emissions.
