CP Piston BRS BBC 24.5CC Dome 4.600 Bore 4.000 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Big Block Chevrolet (BBC) engine, getting the right pistons is crucial for reliability and power. This set of eight forged pistons from CP Pistons is designed for serious builds where strength and precise fitment are paramount. They feature a 24.5cc dome volume, a 4.600-inch bore size, and are intended to work with a 4.000-inch stroke crankshaft and a 6.385-inch connecting rod. This combination is common in many performance BBC applications, helping to achieve a specific compression ratio and displacement.

CP Pistons are well-known for their robust construction, and these are no exception. Forged from high-strength aluminum alloy, these pistons can withstand the extreme pressures and temperatures found in high-output engines. The dome shape is engineered to work with specific cylinder head combustion chamber designs to optimize airflow and combustion efficiency. Because these are made to order, you can be confident they are built to the exact specifications required for your custom engine build. The set includes all eight pistons, ready for your machine shop to install.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or machinist to ensure these pistons are the perfect match for your specific build goals, including your chosen cylinder heads, camshaft, and crankshaft.
