CP Piston Bullet Race Series Small Block Ford 19/20 Deg. 4.030 Bore 4.000 Stroke 6.200 Rod Set Of 8

Forged from high-strength aluminum alloy, these CP Pistons Bullet Race Series pistons are built for serious performance in Small Block Ford engines. The 4.030-inch bore and 4.000-inch stroke combination, paired with a 6.200-inch rod length, is a popular setup for builders looking to increase displacement and power. The 19/20-degree valve angle design is specifically chosen to match many common cylinder head port configurations, helping to optimize airflow and combustion efficiency for maximum output.

These pistons feature a deep valve relief to accommodate larger camshafts and higher lift situations without valve-to-piston contact. The skirt design is optimized for reduced friction and improved piston-to-wall sealing, which contributes to better ring seal and overall engine health under high loads. Each piston is carefully machined to precise tolerances, ensuring a well-built component that can withstand the rigors of racing and high-performance street applications. This set includes eight pistons, ready for your next engine build.

When building a high-performance engine, attention to detail is key. These pistons are designed to work with specific cylinder head valve angles and rod lengths, so ensure your chosen components are compatible. Because these are intended for racing applications, they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
