Sportsman Racing Products 261357 SBC Domed Forged Piston Set, 4.040-Inch Bore, +6.5 cc, Set of 8

Build dependable performance into your small block Chevy engine with the Sportsman Racing Products 261357 domed forged piston set. Designed for 302 applications, this matched set includes eight pistons engineered for strength, durability, and consistent operation in performance-oriented engine builds. The domed crown and positive 6.50 cc volume support compression-focused combinations when properly matched with the cylinder head, gasket, and rotating assembly specifications.
The 261357 pistons feature a 4.040-inch bore size and a 1.800-inch compression height for compatibility with selected small block Chevy applications. Forged construction provides a strong foundation for demanding street, strip, and competition use, while the precise design helps support reliable piston-to-cylinder-wall performance when installed with the correct clearances and components. Always verify bore size, compression height, deck clearance, valve relief requirements, and compression ratio before installation.
Each piston uses 1/16-inch, 1/16-inch, and 3/16-inch ring grooves, allowing use with compatible piston ring sets selected for the engine’s intended operating conditions. This Sportsman Racing Products piston set is supplied as a complete set of eight, making it a practical choice for rebuilding or upgrading a compatible small block Chevy V8. Professional installation and careful measurement are recommended to ensure proper fitment, ring gap, clearance, and overall engine performance.
