* Engine Mounts: Motorhome engines often use different mount locations and patterns than those found in a 1967 Charger. You'll likely need custom engine mounts fabricated. This requires significant fabrication skills and possibly access to specialized equipment.
* Transmission: Motorhome engines often use different transmissions than those originally in a Charger. Adapting the transmission to the Charger's drivetrain will require extensive work, possibly including custom driveshafts, bellhousing modifications, or even a complete transmission swap.
* Wiring Harness: The motorhome's wiring harness is not compatible with the Charger's electrical system. You'll need to either completely rewire the car to accommodate the motorhome's system (a massive undertaking) or meticulously adapt the wiring harness, which is highly complex.
* Exhaust System: The motorhome's exhaust system is almost certainly not compatible. A custom exhaust system will need to be built to fit the Charger's chassis and comply with emission regulations (where applicable).
* Cooling System: Motorhome engines may have different cooling system requirements (radiator size, fan setup, etc.) than a Charger. You'll need to ensure adequate cooling capacity.
* Computer/ECU: Modern motorhome engines may have electronic control units (ECUs) that require significant adaptation or replacement to work correctly in the Charger.
* Body Modifications: Depending on the size and specifics of the motorhome engine, you may need to make modifications to the Charger's engine bay to accommodate it. This could involve significant bodywork.
In short: This is not a weekend project. It requires advanced mechanical skills, fabrication expertise, welding abilities, and potentially specialized tools. It's a project better suited for experienced hot-rodders or professional mechanics. The cost of parts, labor, and potential setbacks could be substantial. Unless you have extensive experience with engine swaps and fabrication, it's strongly recommended to seek professional assistance.
