CP Piston BRS Big Bock Chevy 564 4.530 Bore 1.220 +46.9CC Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Big Block Chevy engine and need pistons that can handle serious power, this set from CP Pistons is a solid option. These are forged pistons, meaning they start as a solid block of aluminum that's heated and forced into shape under extreme pressure. This process creates a much stronger and more durable piston than cast aluminum, which is crucial when you're pushing the limits of displacement and compression.

This particular set is designed for a 4.530 inch bore size, and features a 1.220 inch compression height with a dish volume of +46.9cc. This dish volume is important because it directly affects your engine's compression ratio when paired with your cylinder heads and gasket thickness. The BRS series from CP Pistons is known for its robust construction, intended for applications where reliability under stress is paramount. Each piston in this set of 8 is well-made to ensure consistent performance across all cylinders.

Keep in mind that these pistons are made to order and are non-cancelable once production begins. Also, they are not CARB approved and cannot be shipped to California. For any custom engine build, especially one involving a Big Block Chevy, choosing the right internal components like pistons is critical for long-term success and performance. Ensure you consult with your engine builder or refer to detailed engine build specifications to confirm these pistons meet your specific requirements.
