CP Piston Bullet Race Series Chevy LS3 377Ci Afr LS3 12 4.070 Bore 1.300 Ch -3.8CC Flat Top Set Of 8

This is a set of CP Pistons Bullet Race Series forged pistons designed for Chevy LS3 engines, specifically built for a 377 cubic inch displacement with a 4.070 inch bore. These pistons feature a flat top design with a -3.8cc dish, and they utilize a 1.300 inch compression height. This set includes eight pistons, intended for 8-cylinder applications like the LS3 engine.

CP Pistons is known for producing well-built internal engine components, and this Bullet Race Series set is no exception. Forged from high-strength aluminum alloy, these pistons are built to withstand the increased cylinder pressures and temperatures found in performance and racing applications. The 4.070 inch bore size is a common upgrade for LS3 engines looking to increase displacement, and the -3.8cc flat top dish is designed to work with specific compression ratios, often paired with aftermarket cylinder heads like those from AFR (Airflow Research) to achieve optimal performance. The 1.300 inch compression height is crucial for proper piston-to-valve clearance and deck height, ensuring correct engine assembly and operation.

When rebuilding or significantly upgrading a Chevy LS3 engine, especially for racing or high-performance street use, choosing robust internal components like these forged pistons is essential. They are designed to handle significantly more stress than cast pistons. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic for specific assembly details, including ring gap, bearing clearances, and proper installation procedures to ensure the longevity and performance of your engine build.
