CP Piston BRS Chevy 429Ci Ascs 4.130 Bore 1.000 Ch 14:1 Cr - Set Of 8 (MTO Non-Cancel)

This set includes eight forged pistons from CP Pistons, designed for Chevy 429ci applications. Each piston features a 4.130-inch bore and a 1.000-inch compression height, contributing to a 14:1 compression ratio. These pistons are built for performance, utilizing a strong forged construction that can handle higher cylinder pressures and temperatures compared to cast pistons. The BRS series is known for its robust design, intended for engines that see significant use and demand reliability under stress. Because these are made-to-order, they offer a unique opportunity to get a specific configuration for your build, but please note they cannot be canceled once ordered.

The forged aluminum construction is key here. It means the pistons are formed under extreme pressure, aligning the grain structure of the metal for superior strength and fatigue resistance. This makes them well-suited for high-performance builds where detonation or excessive heat might be a concern with lesser components. The 14:1 compression ratio is quite high, indicating these are intended for naturally aspirated engines that require premium fuel and careful tuning to achieve maximum power output. The 1.000-inch compression height is a specific measurement that dictates how the piston sits in the cylinder relative to the deck surface, critical for achieving the target compression ratio and proper valve-to-piston clearance.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Given the high compression ratio, ensuring proper engine assembly, including accurate timing and a well-functioning cooling system, is paramount for longevity and performance. These pistons are a significant upgrade for anyone looking to build a powerful and durable Chevy engine, but they are not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified professional for specific installation and tuning advice tailored to your application.
