There is a local shop that is known worldwide for putting in the V8 hemi in almost everything. My buddy dusty does most of the engine swaps, Scott is a very smart guy also does alot with lifting vehicles, and Dan the owner is a crazy jeep god. They have done work on all my jeeps and my crossfire. They were looking into putting a hemi in my brothers prowler but the 6.1 will not fit. They have thrown a viper engine in jeff christistys wrangler and even have created a wrangler srt8 Check out the site and dream away. http://www.burnsvilleoffroad.com/
