CP Piston Bullet Race Series Big Block 4.600 Bore 4.250 Stroke 6.535 Rod 1.120 Set Of 8

Forged from high-strength aluminum alloy, these CP Pistons Bullet Race Series pistons are built for big block engines where serious performance is the goal. With a 4.600-inch bore and a 4.250-inch stroke, they are designed to handle the demands of high-horsepower applications. The 6.535-inch rod length is a critical measurement that dictates the piston's position in the cylinder throughout its rotation, impacting compression and overall engine balance.

Each piston in this set of 8 features a 1.120-inch compression height, which is the distance from the wrist pin center to the top of the piston crown. This measurement, along with the bore and stroke, determines the engine's compression ratio when paired with the correct cylinder heads and crankshaft. CP Pistons is known for its precision manufacturing, ensuring that each piston meets tight tolerances for consistent performance and reliability under extreme conditions. These are a popular choice for builders looking to maximize power output from their big block V8.

Because these pistons are not CARB approved, they cannot be shipped to California. Please verify fitment and compatibility with your specific engine build before ordering. If you are building a high-performance big block, these pistons offer a solid foundation for significant power gains.
