Customer Questions & Answers

  • Question: What are hypereutectic pistons and how do they benefit my Chevy small block 350?

    Answer: Hypereutectic pistons are made with a specific alloy that allows for improved performance and durability compared to traditional cast pistons. They expand less than regular pistons when heated, reducing the chances of seizure in high-temperature applications. This makes them an excellent choice for high-performance engines or those subjected to high stress, improving engine longevity and efficiency.
  • Question: What does the .020 over size mean for these pistons?

    Answer: The .020 over size indicates that these pistons have a diameter that is 20 thousandths of an inch larger than the standard size for a small block 350 engine. This sizing allows for a more precise fit and can help accommodate for wear in the cylinder walls, ensuring better compression and overall performance. It's essential for builders looking to maximize power and efficiency.
  • Question: Are these pistons suitable for both street and race applications?

    Answer: Yes, the hypereutectic flat top pistons are designed to perform well in both street and racing applications. They provide improved thermal stability and reduced friction, making them versatile. Whether you are building a daily driver that needs reliability or a high-performance machine for the track, these pistons can meet your needs effectively.
  • Question: What is the advantage of using moly rings with these pistons?

    Answer: Moly rings are made from a material that provides excellent wear resistance and creates a good seal against combustion gases. When paired with hypereutectic pistons, they enhance performance by minimizing oil consumption and improving compression. The synergy between moly rings and these pistons ensures that your engine runs more efficiently and with better longevity.
  • Question: What are valve reliefs and why are they important?

    Answer: Valve reliefs are cutouts in the piston that allow for clearance between the piston and the valves during engine operation. They are crucial in high-performance applications to prevent valve contact with the piston, which can lead to severe engine damage. The 4 valve relief design helps to accommodate higher lift camshafts, making it suitable for performance builds.
  • Question: Can I install these pistons without professional help?

    Answer: While a skilled DIY mechanic may install these pistons, it is generally recommended to seek professional help to ensure proper installation. This includes accurate measuring, fitting, and assembly, which are vital for optimal engine performance. Professional mechanics have the tools and experience necessary to avoid common pitfalls, ensuring your engine operates at peak efficiency.
  • Question: Do I need to make modifications to my engine for these pistons?

    Answer: In most cases, no major modifications are necessary if you are replacing old pistons with these hypereutectic ones, especially if you're using them in a stock cylinder setup. However, if your engine has been significantly modified or has after-market components, it may require some adjustment. It is always best to check compatibility with your engine specifications.
  • Question: Where can I find a bundled set of 8 .020 over size hypereutectic pistons and matching moly rings?

    Answer: You can purchase a bundled set of (8) .020 oversize hypereutectic flat top 4 valve relief pistons along with matching moly rings from Ubuy in Isle of Man. Ubuy provides a variety of automotive performance parts to ensure you have access to the products you need for your Chevy small block 350.
  • Question: How do I properly break in new pistons and rings?

    Answer: Breaking in new pistons and rings is crucial for ensuring a proper seal and maximizing engine performance. It typically involves running the engine at varying RPM ranges for a specified period to allow the rings to seat correctly. Following manufacturer guidelines for break-in procedures will lead to better longevity and performance of your engine components.
  • Question: What kind of performance gains can I expect with these pistons?

    Answer: Using hypereutectic pistons can lead to significant performance improvements. These gains often include increased horsepower, better fuel efficiency, and enhanced throttle response. The flat top design also contributes to improving the compression ratio, which further boosts performance. Engine enthusiasts often notice these benefits through improved acceleration and overall engine responsiveness.
