Hello there, I've got a 2003 Mustang GT. And I also had a 2000 Mercury Grand Marquis. , the Grand Marquis Add a rod through the oil pan. The Mustang had a blown head gasket or warped heads. I decided. To take the heads off of the Mercury and do the swap? But I had a problem with the Cam position. Sensor .Does anyone know What I need to do to make this Mustang run good? Any help would be awesome and. It seems like I don't know what I'm talking about. Because I don't know what I'm talking about. Brand new to this.

This is not a recommended swap. Why? Because a 2000 Panther has non-PI heads. To get PI head the motor needs to come from a 2002+ Panther.

If this is done expect this to run poorly because the PCM is tuned for PI heads and will not run well with the NON-PI heads.

If looking for possible donors recommend staying away from the 2002 model year as this has the PI heads with too few spark plug threads. The 2003+ has the better designed PI heads.

Go to www.car-part.com. Look for salvage yards in your area that has a motor from a 2003+ Grand Marquis or Town Car (Panther). IMO you would be much smarter to buy a whole salvage motor than attempting any in vehicle repair. You could also look for a Mustang motor but expect to pay extra.

In order to use a whole Panther motor you are going to need the Mustang specific parts from the original motor.

Today's salvage yards generally do not keep motor parts (only whole motors). Likely it would be the same price to find the heads as what the whole motor would cost. I personally would prefer to perform a motor swap than a in car head swap. Not to mention that using the whole motor saves the cost of gaskets and the work associated with major engine work.

Another thing to consider. When the short block of the original motor was re-used aren't you relying upon it being in good condition without really performing any tests?

When the old motor is out, either sell the parts or use it for a different project. Because salvage yards don't sell motor parts there are plenty of people out there looking for parts. I had no problems selling parts from my old blown up 2000 GT.

It might be useful to tell us what are the symptoms and DTC's with the motor that you have. I would expect that a non-PI motor into a PI car would not make maximum power. However I would expect it to run at lower power levels (idle and part throttle).

Tell us about any "mix and matching" of parts were done. For example mixing a PI intake on the non-PI heads. Or using parts from the 2000 instead of the car's originals.

If there's a cam related DTC remember that these "might" be caused by a bad alternator diode.
