I. Engine and Transmission:
* 350 Chevy Small Block Engine: Source a complete engine, ideally already rebuilt or in excellent condition. Consider the year and specific model of the 350 as different variants have different characteristics.
* Transmission: You'll need a transmission compatible with the 350. A TH350, TH700R4, or even a modern automatic would work. You'll need the transmission bellhousing appropriate for the chosen transmission and the 350 block. Manual transmission options exist, but adapting the AMC's clutch and linkage will add complexity.
* Torque Converter (If using an automatic): Must be compatible with both the 350 and your chosen automatic transmission.
II. Engine Mounts and Accessories:
* Motor Mounts: These are absolutely crucial. You won't find bolt-in mounts. You'll either need to fabricate custom motor mounts or purchase a kit specifically designed for a Chevy small-block swap into an AMC Eagle (if one even exists – this is likely the most challenging part). This will involve significant welding and fabrication skills.
* Oil Pan: The AMC Eagle's frame likely won't have clearance for a standard 350 oil pan. You'll probably need a specialized shallow pan.
* Exhaust Manifolds or Headers: Custom headers are highly recommended for clearance and performance. Manifolds will likely require modification or fabrication.
* Alternator, Power Steering Pump, and other Accessories: You'll need to adapt the mounting brackets for these components to fit the new engine and the AMC Eagle's accessories. Consider using brackets from a similar-sized engine to simplify the process.
III. Drive Train and Related Components:
* Driveshaft: The AMC Eagle's original driveshaft will almost certainly be incompatible with the new transmission and engine. You'll need a custom driveshaft made or significantly modified.
* Transmission Crossmember: This will likely need to be modified or replaced to accommodate the new transmission.
* Clutch (If using a Manual Transmission): A complete clutch assembly suitable for the selected transmission and the engine's output.
IV. Fuel System:
* Fuel Pump and Lines: You'll need to adapt or replace the fuel pump and fuel lines to work with the Chevy 350. High-performance fuel pumps might be necessary.
* Fuel Tank: Depending on the chosen fuel system, you may need to modify or replace the fuel tank.
V. Cooling System:
* Radiator: You might need a larger capacity radiator to handle the 350's increased heat output.
* Radiator Hoses: Custom radiator hoses are almost certainly necessary.
* Water Pump: Compatible with the 350.
VI. Electrical System:
* Wiring Harness: You'll need to adapt the existing wiring harness or create a custom one to accommodate the Chevy 350's electrical system. This is a very complex part of the swap.
* Computer Control (if applicable): Depending on the year and setup of the 350 engine, you might need to deal with engine control modules (ECMs) and associated wiring.
VII. Other Necessary Items:
* Welding Equipment (likely): For fabricating motor mounts, exhaust, etc.
* Various Tools and Equipment: A complete set of automotive tools, including a lift or jack stands.
* Patience and Perseverance: This is a major project that will require significant time and effort.
VIII. Research and Planning:
* Consult AMC Eagle Forums and Communities: Connect with enthusiasts who have completed similar swaps. They can provide invaluable advice and tips.
* Detailed Plans and Drawings: Before you begin, create thorough plans, including measurements and diagrams, for all modifications.
This is not an exhaustive list, and unforeseen challenges will undoubtedly arise. This swap is best tackled by experienced mechanics with fabrication skills. Unless you possess considerable mechanical expertise, consider seeking professional help to complete this ambitious project. Failing to properly address these components could lead to a dangerous and unreliable vehicle.
