SBC F/T Piston Set 4.060 Bore -7cc

The SBC F/T Piston Set 4.060 Bore -7cc is an essential upgrade for engine builders looking to optimize the performance and reliability of a Small Block Chevy engine. These flat-top pistons are designed specifically for high-performance street and mild racing applications where consistent compression and durability are paramount. By utilizing a 4.060-inch bore size, this set allows for precise cylinder wall fitment during a comprehensive rebuild or overbore project. This complete set of eight pistons provides the necessary foundation for a balanced rotating assembly in various classic and modern Chevy engine configurations.

Constructed from high-silicon hypereutectic aluminum alloy, these pistons offer superior thermal characteristics and reduced expansion compared to standard cast alternatives. This material choice allows for tighter piston-to-wall clearances, which improves ring seal and reduces engine noise during cold starts. The design features a -7cc valve relief volume to accommodate performance camshafts while maintaining efficient combustion chamber dynamics. Furthermore, the machined ring grooves are sized at 5/64, 5/64, and 3/16 inches to accept standard high-performance ring sets for maximum oil control and compression maintenance.

Engineered for the Small Block Chevy platform, this piston set is ideal for enthusiasts seeking a reliable balance between power output and long-term service life. The flat-top profile is particularly effective for those aiming to achieve specific compression ratios when paired with various cylinder head combustion chamber volumes. Installation should be performed by a qualified machinist to ensure proper bore sizing and rotating assembly balance for optimal results. Whether you are refreshing a classic cruiser or building a spirited street machine, these KB Performance pistons deliver the engineering precision required for modern performance standards.
