Year for year and size for size they are a direct swap. In other words, a 5.4 from an F150 is the same as a 5.4 from an Expedition. There are also years that will interchange but I am not certain which ones are direct swaps. The Expedition is based on the F150 platform.
The 1989 F150 came with a 4.9 L ( 300 cubic inch) straight six , 5.0 L ( 302 cubic inch) V8 or 5.8 L ( 351 cubic inch ) V8 engine
4.2 liter V6 , 4.6 liter V8 , or 5.4 liter V8
