We've got the HEMI engine sitting in the Green TJ and are awaiting the long arm kit! Before it leaves, the Green Machine will get super built Dana 60s. We are also installing a Comp cam to bump up the HP!  The basic build is straightforward like any other TJ engine swap.  Removal of the old mounts, careful mounting of the new ones.  Basic items like leveling the engine, checking for exhaust clearance are also important.  The swap deviates from the norm when the wiring and evap systems are introduced. 

Here are a few photos of the Red TJ at the SEMA show.
