CP Piston Bullet Race Series Big Block 4.600 Bore 4.375 Stroke 6.535 Rod 1.070 Set Of 8

Forged from high-strength 2618 aluminum alloy, these CP Pistons Bullet Race Series pistons are built for the demands of serious Big Block engine builds. The 4.600-inch bore and 4.375-inch stroke dimensions are specifically chosen for performance applications, working in conjunction with a 6.535-inch rod length and a 1.070-inch compression height. This combination is designed to achieve optimal compression ratios and piston-to-valve clearance in many popular Big Block configurations.

CP Pistons is well-known for its commitment to precision manufacturing, and this set is no exception. Each piston in this set of eight undergoes rigorous quality control to ensure consistency and reliability. The 2618 aluminum alloy offers a good balance of strength and weight, crucial for high-RPM operation where reducing reciprocating mass is key. These pistons are intended for builders who need a solid foundation for a powerful engine, whether for drag racing, circle track, or other demanding motorsports.

When building a high-performance Big Block, the details matter. This set includes pistons, wrist pins, and locks, ready for assembly. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or machine shop for specific clearance checks and assembly recommendations to ensure the best possible outcome for your project.
