Customer Questions & Answers
-
Question:
What are Hypereutectic pistons, and why are they beneficial?
Answer: Hypereutectic pistons are engineered to withstand high temperatures and reduce thermal expansion, making them highly durable. This material composition allows for better wear resistance and this leads to enhanced longevity in performance applications. When used in a Chevy 350 small block, they can effectively optimize engine performance while maintaining efficiency. -
Question:
What is the advantage of flat-top pistons over dished pistons?
Answer: Flat-top pistons increase the compression ratio, leading to more power output without requiring extensive modifications. This is particularly advantageous in performance builds, where maximizing engine efficiency is critical. For those looking to enhance horsepower in their 1968-85 Chevy 350 small blocks, flat-top pistons provide a straightforward solution. -
Question:
How do valve reliefs in pistons impact engine performance?
Answer: Valve reliefs are cutouts that allow for the clearance necessary to avoid contact with the valves during operation. This is crucial for high-performance engines, particularly those with modified camshafts. For the Chevy 350 small block, having proper valve reliefs can ensure that you can run higher lift cam profiles without risk of damage. -
Question:
What does a .030 over size mean for pistons?
Answer: The .030 over designation indicates that the pistons are designed for a cylinder bore that is 0.030 inches larger than stock. This sizing accommodates for wear or damage in the engine block, allowing for a proper fit while optimizing engine performance. It is specifically tailored for those performing comprehensive rebuilds on their Chevy 350 small blocks. -
Question:
What types of rings come with the bundled set?
Answer: The bundled set includes matching Moly rings, which are designed to provide excellent wear resistance and reduce friction in the engine. Moly rings are known for their durability and improve the sealing capability within the cylinder. This results in better compression and overall engine efficiency, key aspects for those rebuilding their Chevy 350 engines. -
Question:
Are these pistons suitable for street and racing applications?
Answer: Yes, these Hypereutectic flat-top pistons are versatile enough for both street and racing applications. They combine durability with efficiency, making them a superb choice for daily drivers seeking reliability and race engines requiring high performance. Their performance and heat resistance make them a favorite among those who demand the best from their Chevy 350 small blocks. -
Question:
What is the typical installation process for these pistons?
Answer: Installation of these pistons involves disassembling the engine, honing the cylinder walls, and then carefully fitting the new pistons into the connecting rods. Professional help or detailed instructions are recommended to ensure proper clearance and alignment. This installation process is fundamental for achieving the desired performance from your Chevy 350 small block. -
Question:
Can I use these pistons in a modified engine?
Answer: Absolutely! These pistons are designed to complement modifications often done to the Chevy 350 small block, such as upgraded camshafts or cylinder heads. Their construction allows for adjustments in performance-enhancing scenarios, making them a fitting choice for anyone looking to boost their engine output. -
Question:
Where can I buy a bundled set of 8 .030 over Hypereutectic Flat Top 4 Valve relief Pistons and matching Moly Rings compatible with 1968-85 Chevy 350 small blocks?
Answer: You can purchase a bundled set of 8 .030 over Hypereutectic Flat Top 4 Valve relief Pistons and matching Moly Rings through Ubuy.
