CP Piston Bullet Race Series Small Block Ford 19 / 20 438 Ci 4.125 1.250 +5.77CC Set Of 8

CP Pistons is well-known for making high-performance internal engine components, and this Bullet Race Series piston set for Small Block Ford engines is a prime example of their work. If you're building a serious performance engine, especially a 438 cubic inch stroker using a 4.125 inch bore, these pistons are designed to handle the demands of racing and high-output street applications. They are forged from strong materials to withstand the extreme pressures and temperatures found in powerful V8s.

This set is specifically engineered for a 4.125 inch bore with a 1.250 inch compression height, and each piston features a +5.77cc dish volume. This dish volume is important for tuning your compression ratio, allowing you to achieve your target with different head chamber sizes. The Bullet Race Series is built for durability and performance, using advanced forging techniques to create a strong yet relatively lightweight piston. This helps reduce reciprocating mass, which can lead to improved engine response and higher RPM capabilities. The set includes eight pistons, ready for your next engine build.

When installing these pistons, ensure you follow the manufacturer's recommended clearances and lubrication procedures for optimal performance and longevity. Because these are performance racing pistons, they are not CARB approved and cannot be shipped to California. Always consult your engine builder or the CP Pistons technical documentation for specific installation details and tuning recommendations to get the most out of this set.
