No, this can not be done with minimal difficulty. Wiring harness, emissions, exhaust system would all need to be modified.


No, it will take an enormous amount of work and some design changes to even begin to get that to work, plus emission systems will no longer operate so if you have inspections it will fail. The Bronco is pre-OBD2 so that engine is only going to work in pre- OBD2 Ford vehicle, so something before 1996 in the Ford line.


The 5.4 is a better engine anyway.
