CP Piston BRS BBC 509 Ci 4.500 1.245 Ch +46.9CC Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS forged pistons, specifically made for a 509 cubic inch Big Block Chevrolet (BBC) engine. These pistons feature a 4.500 inch bore size and a 1.245 inch compression height, with a dish volume of +46.9cc. They are designed for high-performance applications where strength and reliability are paramount.

CP Pistons is known for making well-built internal engine components, and this set is no exception. The BRS series uses a strong aluminum alloy designed to withstand the high pressures and temperatures found in powerful V8 engines. The forged construction means these pistons are significantly stronger and more durable than cast pistons, making them ideal for racing or heavily modified street engines. The specific dish volume is important for achieving your desired compression ratio when paired with your cylinder heads and gasket thickness. This set is made to order and cannot be canceled once placed.

When rebuilding or upgrading a large displacement BBC engine, pistons are a critical component. These CP Pistons are built to handle the demands of a 509 cubic inch application. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer specifications for proper installation and compatibility with other engine components.
