If you are looking for MPGs i would go with a diesel. 4BT swaps are getting more common.

Would like to do a drivetrain swap in the future and always like to see what others have done before making any final decisions on what parts I want to use.

How about any of you that have done a 5.0, 5.3, Ls1 or Ls2 swaps?
