CP Piston BRS SBC 4.030 Bore 3.500 Stroke 5.7 Rod 1.550 Set Of 8 (MTO Non-Cancel)

This is a set of eight forged pistons from CP Pistons, specifically designed for Small Block Chevrolet (SBC) engines. These pistons feature a 4.030 inch bore, a 3.500 inch stroke, and are designed to work with a 5.7 inch connecting rod. Because these are made to order, they are non-cancelable once production begins, so double-check your specifications before ordering.

CP Pistons are well-known in performance circles for their robust construction and attention to detail. These particular pistons are forged from high-strength aluminum alloy, which offers a great balance of durability and weight savings. The 4.030 inch bore size is a common upgrade for SBC engines, allowing for increased displacement and potential power gains when paired with the correct crankshaft and connecting rods. The 3.500 inch stroke and 5.7 inch rod length are also critical dimensions that determine the engine's overall displacement and piston-to-rod angle, impacting performance and longevity. The 1.550 inch compression height is also a key measurement that dictates the piston's position in the cylinder at Top Dead Center, which directly affects the compression ratio when used with a specific cylinder head volume and head gasket thickness.

This set includes all eight pistons needed for a V8 engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance SBC engine and need reliable, well-built internal components, this set from CP Pistons is a solid option. Remember to consult your engine builder or a trusted mechanic to ensure these specifications align with your build goals.
