CP Piston BRS BBC 571Ci 4.625 Bore 1.275 Ch 14.3:1 Cr Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS BBC pistons, designed for a 571 cubic inch engine with a 4.625 inch bore. These pistons are forged from high-strength aluminum alloy, a common choice for performance applications because it offers a good balance of strength and weight. They are built to achieve a 14.3:1 compression ratio, which is quite high and typically suited for naturally aspirated racing engines or those running high-octane fuel. The compression height is 1.275 inches, a critical measurement that determines the piston's position in the cylinder at top dead center relative to the crankshaft centerline. This specific set is made to order, meaning it's manufactured specifically for your purchase and cannot be canceled once production begins.

CP Pistons is known for making well-built components for serious engine builds. These BRS series pistons are designed for durability under demanding conditions. The forged construction means they start as a solid block of aluminum that is heated and then pressed into shape, creating a grain structure that is much stronger and more resistant to fatigue than cast pistons. This strength is essential for handling the high cylinder pressures and temperatures found in large displacement, high-compression engines. The 4.625 inch bore size indicates these are intended for a big block Chevrolet engine configuration, often used in drag racing, circle track, or high-performance street applications where maximum power output is the goal.

Because these pistons are made to order, please allow for manufacturing time. They are not CARB approved and cannot be shipped to California. If you are building a high-performance engine that requires robust internal components to handle significant power, this set of CP Pistons offers a solid foundation.
