If you're looking for the best spark plugs for your SBC 350, you've come to the right place. Choosing the right spark plugs can make a significant difference in the performance of your engine. However, with so many options available in the market, it can be overwhelming to choose the best one. In this article, we'll provide you with a brief guide on the key points you should consider when looking for the best spark plugs for your SBC 350.
Firstly, it's essential to consider the type of spark plug you need. Copper, platinum, and iridium are the three most common types of spark plugs. Copper spark plugs are the most affordable, but they have a shorter lifespan compared to platinum and iridium spark plugs. Platinum spark plugs are known for their durability and longevity, while iridium spark plugs offer the best performance.
Secondly, you should consider the heat range of the spark plug. The heat range is the measure of how quickly the spark plug can transfer heat from the combustion chamber to the engine's cooling system. Choosing the wrong heat range can lead to engine damage or reduced performance.
Thirdly, it's essential to consider the electrode gap. The electrode gap is the distance between the center and ground electrodes. This gap affects the spark plug's firing efficiency, and it's crucial to choose a spark plug with the correct electrode gap.
Fourthly, you should consider the brand reputation and customer reviews. Choose a brand with a good reputation for quality and reliability. Reading customer reviews can give you an idea of the spark plug's performance in real-world conditions.
Lastly, consider the compatibility of the spark plug with your engine. Check your engine's manual or consult with a mechanic to ensure that the spark plug you choose is compatible with your engine.
In conclusion, choosing the best spark plugs for your SBC 350 requires careful consideration of the type of spark plug, heat range, electrode gap, brand reputation, and compatibility. By keeping these key points in mind, you can ensure that you choose the best spark plugs for your engine's performance and longevity.

Best Spark Plugs For Sbc 350 FAQs
Are there any specific features to look for when choosing spark plugs for a SBC 350?
Yes, there are specific features to look for when choosing spark plugs for a SBC 350. The first feature to consider is the heat range. The heat range determines how much heat the plug can dissipate and is important for engine performance and longevity. A hotter plug is better for colder climates, while a cooler plug is better for hotter climates. The next feature to consider is the electrode material. Copper is the most common electrode material but platinum and iridium are more durable and long-lasting. The gap size is also important and should be set according to the manufacturer's specifications. Finally, the thread size and reach must match the engine's specifications. Choosing the right spark plugs can improve engine performance and fuel efficiency while also extending the life of the engine.
Can using the wrong spark plugs cause damage to a SBC 350 engine?
Using the wrong spark plugs can potentially cause damage to a SBC 350 engine. Spark plugs play a crucial role in the ignition process, and using the wrong type can result in incomplete combustion and engine misfires. This can cause a buildup of carbon deposits, reduced power, decreased fuel efficiency, and potentially damage the engine over time. It is essential to use the correct spark plugs recommended by the manufacturer and to ensure they are properly gapped and installed. Using spark plugs with a higher heat range than recommended can also cause pre-ignition and detonation, which can cause engine damage. It is always best to consult a professional mechanic or refer to the owner's manual for the appropriate spark plug selection to ensure optimal engine performance and longevity.
What are the top-rated spark plugs for a small block Chevy 350 engine?
1. AC Delco R45TS – These are the OEM spark plugs and are widely used in Chevy engines. They have a copper core and are known for their reliability.
2. NGK TR55 – These spark plugs are made of high-quality materials and offer excellent performance. They have a nickel alloy tip that provides superior heat dissipation.
3. Champion RC12YC – These spark plugs are known for their durability and are popular with Chevy engine owners. They have a copper core and are resistant to fouling.
4. Bosch Platinum Plus – These spark plugs have a platinum center electrode that provides better performance and longer life. They are also known for their excellent fuel efficiency.
Ultimately, the choice of spark plugs will depend on several factors, including the engine's condition, the driving conditions, and the owner's preferences. It is always best to consult with a professional mechanic or refer to the owner's manual for the recommended spark plugs.
What is the recommended spark plug gap for a SBC 350?
The recommended spark plug gap for a SBC 350 engine is 0.035 inches. This gap ensures that the spark plug generates enough voltage to ignite the air-fuel mixture in the combustion chamber. It is essential to maintain the correct gap to avoid misfires, poor fuel economy, and engine damage.
To set the gap correctly, use a spark plug gap tool that can be found at any auto parts store. First, remove the old spark plugs and inspect them for any signs of wear or damage. Then, use the gap tool to adjust the gap to 0.035 inches for the new spark plugs.
It is important to note that some high-performance engines may require a different spark plug gap, so always check the manufacturer's specifications for your specific engine. Additionally, it is recommended to replace spark plugs every 30,000 miles to ensure optimal engine performance.
What type of spark plugs are best for a high-performance SBC 350 engine?
When it comes to choosing spark plugs for a high-performance SBC 350 engine, there are a few factors to consider. First, the plug's heat range should be matched to the engine's specific needs. A colder plug may be necessary for engines that run hotter or have a higher compression ratio.
Secondly, platinum or iridium-tipped plugs are recommended for high-performance engines as they provide better conductivity and durability than traditional copper plugs. These materials are also more resistant to wear and corrosion, making them ideal for high-stress applications.
Finally, the gap size should be carefully set to ensure optimal ignition and combustion. A smaller gap may be necessary for high-performance engines that require a more powerful spark.
Overall, the best spark plugs for a high-performance SBC 350 engine are those that are designed for maximum durability, conductivity, and ignition performance, such as platinum or iridium-tipped plugs with a suitable heat range and gap size.
