CP Piston Bullet Race Series Big Block Chevy 565Ci 4.600 Bore 1.275 Ch 14.2:1 Cr Set Of 8

This is a set of eight CP Pistons Bullet Race Series forged pistons designed for Big Block Chevrolet engines displacing 565 cubic inches. These pistons feature a 4.600-inch bore and are engineered to achieve a 14.2:1 compression ratio with a 1.275-inch compression height. They are intended for high-performance racing applications where maximum power output is critical.

CP Pistons is known for producing well-built internal engine components, and this Bullet Race Series set is no exception. They are forged from high-strength aluminum alloy, which provides a solid foundation for extreme cylinder pressures and temperatures commonly found in race engines. The 4.600-inch bore size is specific to certain Big Block Chevy configurations, and the 1.275-inch compression height works in conjunction with your specific connecting rod length and crankshaft stroke to achieve the target 14.2:1 compression ratio. This compression ratio is aggressive and suited for racing fuels like methanol or high-octane race gasoline.

When installing these pistons, ensure you are using appropriate connecting rods and a crankshaft that match the 4.600-inch bore and the desired stroke for your 565ci combination. Proper ring gap, piston-to-wall clearance, and balancing of the rotating assembly are crucial for longevity and performance in a race engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified professional for specific installation and tuning recommendations for your application.
