CP Piston BRS BBC 490 Ci 4.280 Bore 4.250 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

Forged from high-strength 2618-T61 aluminum alloy, these CP Pistons are built for serious performance applications. This set is specifically designed for Big Block Chevrolet (BBC) engines displacing 490 cubic inches, featuring a 4.280-inch bore and a 4.250-inch stroke. The included 6.385-inch connecting rods are engineered to work seamlessly with this piston configuration, ensuring proper geometry and reduced stress within the rotating assembly.

This set of eight pistons is a made-to-order (MTO) item, meaning it's built specifically for your order and cannot be canceled once placed. The 2618-T61 aluminum alloy offers a good balance of strength and thermal expansion properties, making it a popular choice for high-performance street and racing engines. The precise machining ensures a consistent fit and reliable operation under demanding conditions. These pistons are designed to be a direct replacement for standard BBC configurations, but always consult your engine builder or a professional mechanic to confirm compatibility with your specific build and desired performance goals.

When rebuilding or upgrading a high-performance Big Block Chevrolet, choosing the right internal components is crucial. These CP Pistons are a solid option for those looking to maximize power and durability. Remember that this part is not CARB approved and cannot be shipped to California.
