2007 3.7L into 2008

[AlaskaDan]

Anyone know if this is an easy swap and drive?
Know a 2006 into 2007 is, done it. But now have the 2007 engine ready and looking for H3 with blown engine.
Found one but its a 2008.

If you have a later build 2007 it should be easy; early build might not be as simple. An early build is defined by the round air filter and later is a flat air filter, among other things. For example, I believe the TCM on the earlier models is integrated into the PCM and it's separated later.

atvspeed may have input as well since he's owned about every year of H3.
