CP Piston Bullet Race Series Ford 434Ci 4.155 Bore 1.195 Ch 12.5:1 Set Of 8

This set includes eight forged pistons from CP Pistons' Bullet Race Series, designed for Ford 434ci applications. These pistons feature a 4.155-inch bore and a 12.5:1 compression ratio, making them a solid choice for performance builds where increased power and efficiency are key goals. The included components are the pistons themselves, ready for installation into your engine.

CP Pistons is known for its well-built racing components, and this set is no exception. The forged construction offers a strong and durable foundation, capable of withstanding the higher stresses found in performance engines. The specific design of the Bullet Race Series aims to optimize combustion and airflow within the cylinder. The 1.195-inch compression height is a critical measurement that dictates the piston's position relative to the crankshaft and cylinder head at top dead center, directly influencing the final compression ratio and piston-to-valve clearance. This particular set is engineered for a 12.5:1 compression ratio, which is a popular choice for naturally aspirated performance engines seeking a good balance between power output and pump gas compatibility, though specific fuel requirements should always be considered for optimal performance and longevity.

When undertaking a performance engine build, attention to detail is paramount. Ensure you have all necessary supporting components, such as appropriate connecting rods, piston rings, and cylinder head gaskets, to achieve the desired compression ratio and ensure proper engine sealing. It's also important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic to confirm compatibility with your specific engine configuration and build goals.
