Here are a few things to consider:
1. Engine Mounts:
The AMC 304 V8 has different engine mount locations compared to the original engine in the 1982 Jeep CJ7. Custom engine mounts may need to be fabricated or adapted to secure the engine properly in the engine bay.
2. Transmission Compatibility:
Ensure that the transmission on your 1982 Jeep CJ7 is compatible with the AMC 304 V8 engine. The original transmission may not be able to handle the increased power and torque of the V8 engine, and you may need to upgrade or adapt the transmission accordingly.
3. Driveshaft Modifications:
The length of the driveshaft may need to be modified to accommodate the different position of the AMC 304 V8 engine in the Jeep CJ7. A custom driveshaft or modifications to the existing driveshaft may be required.
4. Exhaust System:
The exhaust system on the 1982 Jeep CJ7 will likely need to be modified or replaced to accommodate the AMC 304 V8 engine. Custom exhaust headers and exhaust pipes may be needed to fit the new engine's layout.
5. Engine Cooling:
The cooling system of the 1982 Jeep CJ7 may also need upgrades to handle the increased heat generated by the AMC 304 V8 engine. Larger radiators, more powerful water pumps, and additional cooling fans may be necessary.
6. Electrical System:
Additionally, some modifications to the electrical system may be required. The AMC 304 V8 engine may have different electrical requirements compared to the original engine, such as different fuel injection systems or ignition systems. Custom wiring or adapters may be needed to ensure proper engine operation.
Overall, while the AMC 304 V8 engine can fit in a 1982 Jeep CJ7, it will require a range of modifications to make it compatible, including engine mount adaptation, transmission and driveshaft modification, exhaust system adjustments, cooling system upgrades, and electrical system changes. It's advisable to consult with experienced mechanics or Jeep enthusiasts who have previously done such engine swaps before undertaking this project.
