Introduction To Hei Distributors In Chevy 350
HEI stands for High Energy Ignition. This system is popular for Chevy 350 engines. It provides a stronger spark than traditional ignition systems. This leads to better engine performance and efficiency.
One key benefit of upgrading to HEI is improved fuel combustion. A stronger spark ignites the air-fuel mixture more effectively. This can result in better fuel economy and increased power.
Another advantage is reduced maintenance. HEI distributors have fewer moving parts. This means less wear and tear, leading to longer-lasting performance.
Lastly, HEI systems offer easier installation. Most models fit directly into existing setups. This makes upgrades simple and hassle-free for many car enthusiasts.

Setting Up Your Hei Distributor
Setting up your HEI distributor starts with finding the number one plug wire. This wire is crucial for the correct firing order. First, locate the spark plug wire that connects to the number one cylinder. This is usually at the front of the engine on the driver’s side.
Next, turn the engine until the timing mark aligns with the TDC (Top Dead Center) mark on the damper. At this point, the rotor should point directly at the number one terminal on the distributor cap. This is where the number one plug wire goes.
Make sure to connect the remaining wires in the correct firing order, which is typically 1-8-4-3-6-5-7-2 for a Chevy 350 engine. Proper setup ensures optimal engine performance.
Optimizing Hei Distributor Installation
Correctly placing the wires is vital for the HEI distributor. Start with the number one cylinder wire. This wire connects to the post where the rotor points at top dead center (TDC). The firing order for a Chevy 350 is 1-8-4-3-6-5-7-2. Place each wire in clockwise order on the cap. This arrangement ensures the engine runs smoothly.
Timing adjustments are equally important. Check the timing light settings for accuracy. Adjust the timing to match the manufacturer’s specifications. This adjustment affects engine performance and fuel efficiency. A well-timed engine provides better power and throttle response. Regular checks help maintain optimal engine function.
Troubleshooting Common Hei Distributor Issues
Misfiring problems can be frustrating. Check the spark plugs first. Worn or damaged plugs often cause misfires. Ensure all connections are secure and clean. Look for corrosion on terminals as well.
Wiring complications can lead to issues as well. Make sure to follow the correct wiring diagram. Incorrect connections can disrupt the firing order. Double-check that the distributor cap is seated properly.
Always use high-quality wires. Poor wires can cause misfires and other problems. Regular maintenance can help prevent these issues. Keep an eye on your engine for any signs of trouble.
Advanced Tips For Enhanced Performance
Fine-tuning the timing of your HEI distributor can significantly improve engine performance. Start by ensuring the initial timing is set correctly. Adjusting the timing can enhance torque and horsepower. Use a timing light for precise adjustments.
Consider upgrading to a high-performance HEI distributor. This can lead to better spark delivery and improved fuel efficiency. Look for units with adjustable advance curves. These options allow for tailored performance based on your specific engine setup.
Check the spark plug wires. High-quality wires can reduce resistance and enhance performance. Inspect the coil as well; a stronger coil can provide a more powerful spark.
Maintenance And Care For Longevity
Regular checkups are essential for keeping your Chevy 350 running smoothly. Inspect the spark plugs and wires for wear. Replace any damaged components to prevent engine misfires.
Oil changes should occur every 3,000 to 5,000 miles. Check the coolant level and quality regularly. Replace the coolant as needed to avoid overheating issues.
| Component | Replacement Interval |
|---|---|
| Spark Plugs | Every 30,000 miles |
| Wires | Every 60,000 miles |
| Oil Filter | Every oil change |
| Air Filter | Every 15,000 miles |
