Can a Crown Victoria and a Mercury Marquis same year do a engine swap?
Yes, same cars except the badges...
Just make sure you hook up the install motor the way the original motor is set-up. (Sensors, anything electrical, ignition, etc) If they appear the same components, then it will be just fine.
Engine swap on the same years will be easy. Do NOT change ECU with the engine or you will have issues with the anti-theft. In other words leave the computer on the car it came in.
