CP Piston Bullet Race Series Big Block Chevy 24.9CC Dome 4.500 Bore 4.250 Stroke 6.385 Rod Set Of 8

Forged from high-strength 2618-T61 aluminum, these CP Pistons Bullet Race Series pistons are built for serious performance in Big Block Chevy engines. The 24.9cc dome volume is designed to work with specific compression ratios, making them a key component when building a high-performance naturally aspirated or forced induction engine. Each piston is precision-machined to a 4.500-inch bore size, intended for a 4.250-inch stroke crankshaft and paired with a 6.385-inch connecting rod, ensuring proper fitment and geometry within the cylinder.

CP Pistons is known for their advanced manufacturing processes, and this Bullet Race Series set is no exception. The pistons feature a deep 24.9cc dome, which is crucial for controlling compression and optimizing combustion chamber volume. This design detail is vital for tuners aiming for specific power goals, whether that's maximizing naturally aspirated output or handling the pressures of boost. The 2618-T61 aluminum alloy offers a good balance of strength and thermal expansion properties, essential for pistons that endure high temperatures and pressures found in race applications.

This set includes eight pistons, ready for installation in your Big Block Chevy V8. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For builders targeting maximum performance and reliability in a competition engine, these CP Pistons offer a well-built foundation. Always consult with your engine builder or refer to CP Pistons' technical documentation for specific installation requirements and recommended pairings to achieve your desired engine build.
