CP Piston Bullet Race Series Bcrse1021-030 Chevy 355Ci All 23 4.030 Bore - Set Of 8

If you're building a high-performance Chevy 355ci engine, especially one destined for the track or serious street use, a strong set of pistons is fundamental. The CP Pistons Bullet Race Series BCRSE1021-030 set is designed to handle the demands of boosted or naturally aspirated performance applications where reliability and power are key. These pistons are forged from aerospace-grade aluminum, a material chosen for its excellent strength-to-weight ratio, which is crucial for high-RPM operation and resisting detonation.

This particular set is sized for a 4.030-inch bore, which is a common size for many Chevy 355ci builds, often used when boring out a smaller displacement block or as a standard replacement for a 4-inch bore with a slight overbore. The Bullet Race Series is known for its advanced skirt design and robust construction, helping to reduce friction and wear while maintaining structural integrity under extreme cylinder pressures. Each piston in this set of eight is precision-machined to ensure consistent performance across all cylinders, contributing to a smoother running engine and more efficient power delivery.

When undertaking an engine rebuild of this caliber, it's important to ensure all supporting components are up to the task. These pistons are intended for use with performance connecting rods and crankshafts, and you'll want to consult your engine builder or a trusted manual for the correct ring gap, bearing clearance, and assembly procedures to maximize their performance and longevity. Please note that this piston set is not CARB approved and cannot be shipped to California.
