* Engine Mounts: The engine and transmission will not line up with the existing Ford frame. You'll need to fabricate custom engine mounts. This requires significant welding and metalworking skills.
* Transmission: The Dodge transmission (likely a Getrag or automatic) won't bolt up to the Ford transfer case. You'll need an adapter, potentially a custom-made one, or a complete replacement of the Ford transmission and transfer case with compatible Dodge components.
* Wiring Harness: The Dodge engine's wiring harness is completely different from the Ford's. You'll need to either extensively modify the Dodge harness to work with the Ford system or build a completely new custom harness. This is incredibly complex and requires a deep understanding of automotive electrical systems.
* Computer/ECU: The Dodge engine's computer (ECU) is incompatible with the Ford system. You'll need to either find a way to make the Dodge ECU work, potentially with a custom chip or standalone engine management system, or completely rewire the system to work with a different ECU.
* Exhaust System: The Dodge exhaust system will not fit the Ford frame. A custom exhaust system will need to be fabricated.
* Drive Shafts: The drive shafts will likely need to be modified or replaced to accommodate the different transmission and axle configurations.
* Cooling System: The Dodge cooling system may not be compatible with the Ford radiator and cooling system components. You may need modifications or replacements.
* Fuel System: You might need to modify or replace parts of the fuel system to match the requirements of the Dodge engine.
* Brakes: The Ford's braking system might need upgrades to handle the potentially increased weight and power of the Dodge engine.
In short: This is not a project for a novice mechanic. It requires extensive fabrication skills, welding, electrical knowledge, and a deep understanding of automotive systems. It's more akin to a full-on custom build than a simple engine swap. You'll likely need access to specialized tools and equipment. Consider the cost of parts, labor (if you're not doing it yourself), and the potential for unexpected complications. It's highly recommended to consult with experienced mechanics specializing in custom engine swaps before attempting such a project. Many people attempt projects like this and end up abandoning them due to the sheer complexity.
