It features a small-block V8 design with a cast-iron block, and its parts are widely available, making it a popular choice among car builders and restorers. A comprehensive parts diagram breaks down the engine into manageable sections, illustrating how each component interacts within the system.
Main Components of the Chevy 350 Engine
Understanding the primary parts of the Chevy 350 engine is foundational. These components can be broadly categorized into the block, cylinder head, valvetrain, intake/exhaust system, lubrication system, and ignition system.
Engine Block
The engine block is the core of the engine, housing the cylinders, pistons, crankshaft, and other internal parts.
- Cast Iron Block: The foundation, providing strength and durability.
- Cylinder Bores: The cylindrical spaces where pistons move up and down.
- Water Passages: Channels for coolant to prevent overheating.
Cylinder Head
The cylinder head covers the top of the engine and contains vital components related to air intake and exhaust.
- Valves: Intake and exhaust valves that regulate airflow.
- Valve Springs: Keep valves closed under pressure.
- Camshaft: Located in the cylinder head, controlling valve timing.
Valvetrain Components
This system controls the operation of the valves.
- Camshaft: Converts rotational motion into linear motion to open/close valves.
- Pushrods: Transfer motion from the camshaft to rocker arms.
- Rocker Arms: Actuate the valves.
- Valve Lifters: Follow the camshaft lobes to open valves.
Intake and Exhaust System
These components manage air and exhaust gases.
- Intake Manifold: Distributes air to cylinders.
- Carburetor: Mixes air and fuel (for older models).
- Exhaust Manifold: Collects exhaust gases from cylinders.
Lubrication System
Ensures all moving parts are adequately lubricated.
- Oil Pan: Stores engine oil at the bottom of the engine.
- Oil Pump: Circulates oil throughout the engine.
- Oil Passages: Channels within the engine block and head for oil flow.
Ignition System
Responsible for igniting the air-fuel mixture.
- Distributor: Distributes high voltage to spark plugs.
- Spark Plugs: Ignite the fuel mixture in each cylinder.
- Ignition Coil: Converts battery voltage to high voltage.
