* Specific Needs: The "best" spark plug depends on many factors, including:
* Compression Ratio: Higher compression from the supercharger will need a plug that can handle the extra heat and pressure.
* Fuel Type: Are you using gasoline or E85? The type of fuel can impact plug performance.
* Ignition System: What type of ignition system do you have (stock, aftermarket)? This can affect the required heat range and electrode type.
* Driving Habits: Do you drive aggressively or mostly for cruising? This influences the required heat range.
* Testing and Research: Spark plug performance is a very individual thing. What works great for one person's engine setup may not work as well for another's.
Here's how to find the best plugs for your 350 Chevy with a Weiand 177 supercharger:
1. Consult your supercharger manufacturer: Weiand may have specific recommendations for spark plugs with their 177 supercharger.
2. Reach out to a reputable engine builder or performance shop: They can assess your engine's specifics and recommend the right spark plugs.
3. Read online forums and reviews: Search for other 350 Chevy owners with similar setups. They may have valuable insights and recommendations.
4. Consider reputable spark plug brands: NGK, Denso, Autolite, and Champion are all well-respected brands that offer various types of plugs.
Important Considerations:
* Heat Range: This refers to the plug's ability to dissipate heat. Higher compression from the supercharger usually requires a colder heat range plug to prevent pre-ignition.
* Electrode Material: Iridium or platinum plugs are often preferred for their durability and performance, but there are many options.
* Gap: The gap between the electrodes affects ignition efficiency. It's important to check and adjust the gap according to the manufacturer's specifications.
Always follow the specific instructions for your supercharger and engine. Improper spark plug selection can lead to performance issues or engine damage.
