Question f150 4.6 to 5.4 engine conversion

Has anyone converted a 2001 f150 from a 4.6l to a 5.4l engine? Is the automatic OD transmission different? What is required for this conversion?
Are the electronics the same? Do you need to change the mass air flow sensor or plentum? I only have a 6250 lb towing capacity with the 4.6, and the 5.4 would give me a better capicity.
