Will a 5.4 out of a 04 Excursion go into a 03 F-150

Asked by Brad Dec 17, 2017 at 05:17 PM

Question type: Maintenance & Repair

1 Answer

The 03 is probably a 2V engine and the 04 would be a 3V engine which would not be compatible with the 03 ECU. It might be possible if you also swap the ECU and wiring harness but no guarantees. The transmission comparability with the ECU is probably also an issue.
