CP Piston BRS BBC 516 Ci 4.530 1.245 Ch +46.9CC Set Of 8 (MTO Non-Cancel)

These CP Pistons are forged from a high-strength aluminum alloy, specifically chosen for its durability under extreme cylinder pressures. The 4.530-inch bore size and 4.69cc dish volume are designed to work with a 516 cubic inch Big Block Chevy (BBC) engine, aiming for a specific compression ratio when paired with your cylinder heads. The 1.245-inch compression height is a key measurement that determines the piston's position in the cylinder bore relative to the crankshaft centerline, impacting valve clearance and overall engine geometry.

This set includes eight pistons, each meticulously crafted to meet precise specifications. The BRS (Bullet Race Series) designation indicates these pistons are built for demanding performance applications where reliability and consistent power output are critical. CP Pistons is known for its advanced forging processes and tight tolerances, ensuring each piston is well-built and ready to perform. The design accounts for the specific needs of high-performance engines, including features that help manage heat and stress.

Because these pistons are made to order (MTO), they are non-cancelable once production begins. Please verify your engine's exact specifications, including bore, stroke, rod length, and cylinder head volume, to ensure these pistons will achieve your desired compression ratio and valve-to-piston clearance. This set is not CARB approved and cannot be shipped to California.
