1. Engine and Transmission:
* The Engine Itself: You'll need a complete 350ci V8 engine, including the intake manifold, alternator, starter, etc. Consider the year and model of the engine – some are better suited for this swap than others.
* Transmission: The S-10's original transmission won't handle the torque of a 350. You'll need a much stronger transmission, likely a TH350, TH700R4, 4L60E, or a manual transmission like a T56 or similar, along with the appropriate adapter or bellhousing.
* Engine Mounts: Custom engine mounts will be necessary to properly secure the larger engine in the S-10's engine bay. These are usually fabricated or purchased from specialty shops.
2. Drivetrain:
* Rear Axle: The stock rear axle is insufficient for the power of a 350. You'll likely need a stronger axle, possibly from a heavier-duty truck. This often involves a complete rear-end swap.
* Driveshaft: A custom driveshaft will be required to connect the transmission to the rear axle.
* Differential: You may need a higher gear ratio in your differential to compensate for the increased power and torque.
3. Cooling System:
* Radiator: A much larger radiator is crucial to prevent overheating. An aftermarket aluminum radiator is recommended.
* Cooling Fans: More powerful electric cooling fans or a larger mechanical fan will likely be needed.
4. Fuel System:
* Fuel Pump: A higher-capacity fuel pump is essential to supply the larger engine with sufficient fuel.
* Fuel Lines: You may need to upgrade fuel lines to handle the increased flow.
* Fuel Injectors: The stock fuel injectors might not be adequate for a V8.
5. Exhaust System:
* Headers and Exhaust: Custom headers and exhaust system will be needed to fit the engine and clear the frame.
6. Wiring and Electronics:
* Wiring Harness: You'll likely need to adapt or modify the existing wiring harness, or use a custom harness designed for this swap.
* Computer/ECU: You'll need a compatible computer (ECU) to control the engine, potentially requiring a standalone system or extensive modification of the original system.
7. Other Considerations:
* Steering: The added weight of the engine might affect the steering geometry.
* Brakes: Upgraded brakes are strongly recommended for improved stopping power.
* Body Modifications: You might need to modify or reinforce parts of the body to accommodate the larger engine.
* Suspension: Upgraded suspension components might be necessary to handle the increased weight and power.
In short: This is a major project requiring significant mechanical skills, welding experience (likely), fabrication abilities, and access to specialized tools and parts. It's not a weekend project. Many people choose to have professional shops perform this type of swap due to its complexity. Unless you have extensive experience with automotive modifications, it's highly recommended to seek the help of experienced mechanics or specialists in engine swaps. Researching specific forums and communities dedicated to S-10 swaps is invaluable for finding detailed guides, part recommendations, and advice from others who have completed this type of project.
