This is a set of eight CP Pistons BRS BBC pistons, specifically made for big block Chevrolet engines. They feature a 24.9cc dome volume, a 4.625 inch bore size, a 4.750 inch stroke, and are designed to work with a 6.700 inch connecting rod. These pistons are built to order and cannot be canceled once placed, so please confirm your application carefully before purchasing.

CP Pistons are well-known in the performance engine building world for their robust construction and attention to detail. These particular pistons are forged from high-strength aluminum, which gives them the durability needed to handle the extreme pressures and temperatures found in high-performance big block engines. The dome shape is engineered to achieve a specific compression ratio when paired with the correct cylinder head and gasket combination, which is crucial for maximizing power output and efficiency in your build. The 4.625 inch bore size indicates they are intended for a specific large displacement big block Chevrolet application, and the 4.750 inch stroke combined with the 6.700 inch rod length dictates the piston compression height and wrist pin placement. This precise geometry ensures proper piston-to-valve clearance and optimal ring seal.

Because these pistons are made to order, they offer a unique opportunity to get exactly what your custom engine build requires. It's important to note that these are not CARB approved and cannot be shipped to California. If you're building a high-performance BBC engine and need pistons that are built to last and perform under demanding conditions, this set from CP Pistons is a solid option. Always refer to your engine builder's specifications and the manufacturer's installation guidelines for proper fitment and assembly.
