Ok, First things first. Can this be done as a Straight Swap Engine/Trans/PCM? Or are there other things that I would need to change out? I found a 3.8L V6 Supercharged (L67)(L32) with only 150K on it. <--Beats my 215K Motor.

Also, Would keep the old Engine for parts. Obviously there are parts I would not be able to use. But would use what I could.
