I have a 5.0 in 95 bronco and want to put it in a 03 f150. The f150 has a 5.4 in it now that is blown. I am, at best a shade tree mechanic and am way more comfortable with non computerized, aspirated motors. My question is will the computer stuff match up?

 

Older engine into newer truck will create all sorts of problems. The ECU will be looking for sensors and signals that the engine can't supply.

 

Engine mounts won’t line up, the computer won’t control the transmission…even an older carbureted engine you swap engine and plug harnesses back in. What’s the big difference? Don’t overthink this.
