Just put my deposit down for a 6.0L LQ4 and a 4L60e transmission!! My engine swap dreams are finally coming to fruition.
The folks over at Pacific Fabrication were a huge help. They do all the annoying leg work for you including looking in wrecking yards, making sure all of the sensors and accessories are attached and functional, and wiring up a new harness. They then run the motor and send you a video of it running. Now I just need to drive cross country pick up the engine and head to my Dad's garage to do the swap. More on that in May.
