I am considering taking on the headache of swapping my '03 LS6 with a '06 4.2L Supercharged Jaguar AJ-27S engine. As far as I know it shouldn't be too much effort as far as actually fitting the thing in my Ls. If anyone knows of another thread concerning this, or maybe has some personal insight please feel free to share it. I am not concerned as much with the electrical or bolting issues because I plan to completely strip the car to the bare frame and re-do the interior and paint.
