Had an idea...a 5.4 from an 09-10 F150 or 09-14 Expedition swap into my 07 GT. I've only found a few instances of this swap, but it seems like it should be a fairly simple swap. My goal is to have a bigger engine for as cheap as possible. Here's the research I've done so far:
1: Get the 09+ engine to eliminate spark plug issues with the 5.4
2: Both engines are 3v, wiring is the same for sensors and should be a simple tune
3: Connecting rods are a limiting rev factor, new ones will fix this issue
4: Truck intake is too tall for this engine bay, and is geared for torque. Solution is using a pair of intake adapters from Shelby Mike's to use the original 4.6 intake on the 5.4
5: The 3v 5.4 is about 100 lbs heavier, suspension mods will be able to fix sagging, along with weight distribution/lightening
6: Engine lowering mounts will add room at top of engine
7: Possible clearance issues between the driver's exhaust manifold and steering column
For those who may have done this, did I miss anything? Overall, so far I am looking at about $3000 to get an engine, rebuild it, and get a tune. Need to get more info (parts I haven't thought of, exhaust modification) for final numbers before purchasing anything.
