CP Piston Bullet Race Series Bcrs1021-045 Chevy 358Ci All 23 4.045 Bore Flat Top - Set Of 8

What you get in this box is a complete set of eight (8) CP Pistons Bullet Race Series pistons, designed for Chevy 358 cubic inch engines. These pistons feature a 4.045-inch bore and a flat-top design, making them a solid choice for builders looking to put together a strong, reliable engine. CP Pistons is well-known in the performance world for making well-built components that can handle the demands of serious builds.

These aren't just any pistons; they're forged from high-strength aluminum. This forging process creates a much denser and stronger grain structure compared to cast pistons, which is crucial for handling the high pressures and temperatures found in performance engines. The flat-top design is versatile and often used in builds where specific compression ratios are targeted using the cylinder head volume. The 4.045-inch bore size is a common specification for many Chevy V8 applications, especially those built around the 350ci block with a larger stroke or specific bore requirements.

When you're building an engine, especially one that's going to see hard use, the quality of the internal components like pistons really matters. CP Pistons has a reputation for precision manufacturing, ensuring that each piston in the set is uniform and meets strict tolerances. This uniformity is key for balanced engine operation and longevity. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
