You'd need to investigate the specifics of the exact engine models (e.g., year, model code) for both the donor 3.5L and the recipient 3.2L Concorde. Even then, you'd likely need extensive modifications, including:
* Engine Mounts: The 3.5L engine likely has different mounting points than the 3.2L. Custom mounts would need to be fabricated.
* Wiring Harness: The wiring harnesses are almost certainly different. You'd either need to adapt the 3.5L harness to the Concorde's system or rewire significant portions of the car.
* Transmission: Compatibility between the 3.5L's transmission and the Concorde's existing transmission is uncertain. You might need a new transmission, driveshaft, and potentially even differential modifications.
* Exhaust System: The exhaust system would likely need to be custom-fabricated.
* Cooling System: The 3.5L engine may require a different radiator and cooling system components.
* Computer/ECU: The engine control unit (ECU) will be incompatible and will likely need to be replaced or reprogrammed, and might require additional sensors.
In short, while it's *theoretically* possible, it's a significant undertaking requiring mechanical expertise, fabrication skills, and a substantial investment of time and money. It's far from a simple swap. You should research the specific engine codes of both engines to better assess compatibility, and be prepared for a major engine swap project.
