CP Piston BRS BBC 24.9CC Dome 4.500 Bore 4.750 Stroke 6.700 Rod Set Of 8 (MTO Non-Cancel)

CP Pistons BBC5320-STD is a set of eight forged pistons designed for big block Chevrolet (BBC) engines. These pistons feature a 4.500-inch bore and are intended for use with a 4.750-inch stroke crankshaft and a 6.700-inch connecting rod. Each piston has a 24.9cc dome volume, which is a key factor in determining your engine's compression ratio. These are made-to-order and cannot be canceled once placed.

Forged pistons are a significant upgrade over cast pistons, offering superior strength and durability. CP Pistons uses advanced forging techniques to create pistons that can withstand the extreme pressures and temperatures found in high-performance engines. The BRS series is known for its robust construction, making these pistons a solid choice for serious engine builds where reliability under stress is paramount. The specific dome shape and volume are carefully calculated to work with your chosen cylinder heads and camshaft to achieve your target compression ratio and optimize combustion efficiency.

When building a performance BBC engine, selecting the right pistons is critical. These CP Pistons are designed for builders who need a strong foundation for their project. Because these are made-to-order, please allow for manufacturing time. They are not CARB approved and cannot be shipped to California. Ensure you have all necessary supporting components, such as appropriate rings, pins, and bearings, to complete your engine assembly.
