CP Piston Bullet Race Series Chevy 400Ci 4.125 Bore 1.125 Ch 14:1 Cr - Set Of 8

This is a set of eight CP Pistons Bullet Race Series pistons, specifically made for Chevy 400 cubic inch (Ci) engines. These pistons feature a 4.125 inch bore and a 1.125 inch compression height, designed to achieve a 14:1 compression ratio. CP Pistons is well-known for producing high-performance internal engine components, and this Bullet Race Series is built for demanding applications where strength and reliability are critical.

Forged from high-strength aluminum alloy, these pistons are built to withstand the extreme pressures and temperatures found in high-performance racing engines. The Bullet Race Series design incorporates features aimed at improving combustion efficiency and durability under stress. The 14:1 compression ratio is aggressive, meaning these pistons are intended for use with high-octane fuel and engines tuned for maximum power output. They are a standard bore size for the Chevy 400, meaning they fit the stock cylinder bore diameter, simplifying installation if the block is within spec. This set includes all eight pistons needed for a V8 engine.

When building a high-performance engine, especially one aiming for a 14:1 compression ratio, careful consideration of camshaft profile, cylinder head chamber volume, and fuel system is essential to optimize performance and prevent detonation. These pistons are a solid foundation for a powerful naturally aspirated or forced induction build. Please note that this specific piston set is not CARB approved and cannot be shipped to California.
