CP Piston Bullet Race Series Big Block Chevy 4.280 Bore 4.250 Stroke 6.385 Rod Set Of 8

If you're building a high-performance Big Block Chevy engine for serious racing or street/strip use, a strong set of pistons is fundamental. These CP Pistons Bullet Race Series pistons are forged from high-quality aluminum, giving you the durability needed to handle the extreme pressures and temperatures of a powerful engine. They are designed for a 4.280 inch bore, a 4.250 inch stroke, and use a 6.385 inch connecting rod, making them a solid choice for many performance Big Block Chevy applications.

CP Pistons uses a forging process that creates a denser, stronger piston compared to cast aluminum. This is crucial for race engines where detonation or excessive cylinder pressure can quickly destroy weaker components. The Bullet Race Series is known for its robust construction and attention to detail, ensuring each piston can withstand the demands of high horsepower output. This set includes all eight pistons, ready for your engine build. Remember that these pistons are not CARB approved and cannot be shipped to California.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and ring gap settings to ensure optimal performance and longevity. Proper balancing of the rotating assembly, including these pistons, is also key to a smooth-running and reliable engine. Consult your engine builder or the manufacturer's installation guide for specific details on fitting these pistons into your Big Block Chevy.
