Points Distributor to HEI Conversion: How to Upgrade Your Chevy Ignition

Upgrading from a traditional points distributor to a HEI (High Energy Ignition) system can significantly enhance your Chevrolet’s performance and reliability. This guide provides you with practical steps and tips to make the conversion process as smooth as possible.

Why Convert to HEI?

HEI systems offer multiple benefits compared to traditional points ignition:

  • Better Spark: HEI systems provide a stronger spark, which can lead to improved combustion efficiency.
  • Reduced Maintenance: Unlike point systems, HEI has fewer components that wear out, meaning less frequent adjustments.
  • Enhanced Performance: More reliable ignition can improve throttle response and power output.

Tools and Components Needed

Before diving into the conversion, make sure you have the following:

  • HEI distributor (specific to your Chevy model)
  • Ignition coil (if not included with the distributor)
  • New spark plug wires (high resistance or resistance-free)
  • Basic hand tools (screwdrivers, socket set, wire strippers, etc.)
  • Wiring connectors and electrical tape

Step-by-Step Conversion Process

  1. Preparation:

    • Disconnect the car battery to prevent any electrical shorts.
    • Remove the existing points distributor carefully.
  2. Install the HEI Distributor:

    • Place the HEI distributor into the same mounting position as the old one. Ensure it’s seated correctly.
    • If necessary, base idle timing before removing the old distributor can be useful for a straightforward re-install.
  3. Wiring Considerations:

    • The HEI distributor will typically require a 12V positive source of power.
    • Follow the manufacturer’s instructions for connecting the ignition, ensuring correct wiring to avoid any accidents.
    • Don’t forget to use the correct connectors to ensure a solid electrical connection.
  4. Reconnect and Test:

    • Once installed, reconnect your battery. Check for any electrical shorts by turning the key to the ON position while watching for any issues (no sparks).
    • Start the engine. Ensure it runs smoothly and can handle a rev. A little tuning might be necessary to align timing properly.

Troubleshooting Tips

  • If the engine is hard to start or runs poorly, double-check the wiring connections.
  • Ensure that you’ve grounded the HEI distributor properly within your setup.
  • It’s often helpful to consult with specific forums for your Chevrolet model if unique issues arise.

Conclusion

Converting from a points distributor to an HEI system is a worthwhile investment for your Chevy. With better spark and reduced maintenance, you’ll find your vehicle performs reliably for years to come. If you have questions or need additional assistance, feel free to ask below. Happy wrenching!

The points distributor is crucial in managing the timing of your ignition system. It regulates the flow of electricity to spark plugs, ensuring your engine runs smoothly. Understanding this is essential before considering the HEI upgrade.

Exactly! Converting to a HEI system can greatly improve performance and reliability. No more adjusting points, and you get a more consistent spark, which definitely helps in optimizing engine performance!

I’ve always thought the points system was a bit outdated. HEI seems so much more efficient and user-friendly. However, what should I consider before making the switch?

You’ll want to consider the wiring changes necessary and make sure your coil is compatible with the HEI system. It’s not as tricky as it sounds; just read up a bit before you start!

I converted my classic Chevy to HEI last year and the difference was like night and day! It’s more powerful and much less maintenance.

I can only imagine! How was the installation process? I’m a bit nervous about tackling it myself.

Installation was pretty straightforward! Just follow a good tutorial, and you’ll be fine. You might need a few extra tools, but it’s definitely worth it for the enhanced performance.

I’ve found some great video tutorials online that guide you step by step. They make it seem much easier than I thought! Anyone else had good luck with those?

Yes! I used a couple of those and it helped me gain a lot of confidence. Plus, seeing someone else do it made everything clearer.

I’m still on the fence about switching. Some say HEI is way more reliable, but can anyone share if there are any downsides to the conversion?

Well, some purists argue that the original points system offers a certain ‘character’ to the engine. But honestly, I think the benefits of HEI far outweigh that!

On the humorous side, I’ve heard some say that switching to HEI is like upgrading from a rotary phone to an iPhone! Sure, it’s fancy, but do you really need that for your Chevy?

That’s a good one! But honestly, with today’s fuel and environmental standards, HEI seems like the way to go for those looking to modernize their vintage rides.

Wiring can seem daunting, but it’s pretty straightforward. Just follow the diagrams and label everything as you go. It’ll make the install much smoother.

I would recommend using soldered connections instead of crimp connectors. They provide a more reliable contact, especially under high heat conditions.
