4.6 2v Question

The 2008 CV motor will fit with some changes or swapped parts. The exact list of parts will depend upon the donor motor and the exact configuration of the donor motor.

The long blocks are the same but there will be some parts and sensors to swap. As well as some sensors to remove/not connect.

But given you have a complete original Mustang motor to start with, it's a matter of putting both motors on an engine stand and make the donor look like the original.

If the 2001 is a Romeo based engine, the crown vic will work. You need to disconnect the knock sensor and there is another sensor on the driver side head that is unneeded. Everything else will bolt right up.
