Need Help with Chevy HEI Ignition Wiring

Is there a way to tell if my HEI is working without a fancy diagnostic tool? Just trying to keep it simple without breaking the bank!

Yes! You can check for spark by removing a spark plug and grounding it while cranking the engine. If you see a nice blue spark, you’re on the right track!

Just remember to be cautious when doing this. Always ensure the area is clear and avoid shocks by grounding properly.

Can anyone share their experience with HEI conversions? I’m thinking of upgrading my ignition system.

Upgrading can definitely improve performance! Just make sure to match components correctly to avoid compatibility issues. There are great kits available that simplify the process.

One last tip: if your vehicle is still misfiring, check your ground connections. Poor ground can cause all sorts of issues that can seem like ignition system problems!

Exactly! Grounds are often overlooked. It’s always wise to check those before diving deeper into the ignition system.
