CP Piston BRS BBC 24.35CC Dome 4.280 Bore 4.000 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight forged pistons from CP Pistons, specifically designed for BBC (Big Block Chevrolet) engines. You get the pistons themselves, ready for installation. These aren't just any pistons; they're built with a BRS (Bullet Race Series) design, featuring a 24.35cc dome volume, a 4.280-inch bore size, and are intended to work with a 6.385-inch connecting rod. This specific configuration is crucial for achieving your desired compression ratio and engine displacement, especially when building a high-performance or racing engine.

CP Pistons is known for their commitment to precision and performance, and this set is no exception. The forged construction means these pistons start as a solid block of aluminum that's heated and hammered into shape, creating a much stronger and more durable grain structure than cast pistons. This makes them ideal for handling the extreme pressures and temperatures found in powerful engines. The 24.35cc dome shape is carefully calculated to work with specific cylinder head volumes to achieve a target compression ratio, which is a key factor in engine power and efficiency. The 4.280-inch bore size is a common dimension for many big block builds, and the 6.385-inch rod length is also a standard measurement that ensures proper piston-to-rod geometry.

Because these pistons are made to order (MTO), they are non-cancelable once the order is placed. This means you're getting a fresh set built specifically for your application. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a serious performance engine and need reliable, strong pistons that are built to handle abuse, this set from CP Pistons is a solid option.
