BBM Flat Top Piston Set 4.280 Bore -8cc

The BBM Flat Top Piston Set 4.280 Bore -8cc is a high-performance piston set designed for engine builders looking to enhance the performance of their Mopar B-Series big block engines, particularly the 383 and 400 cubic inch variants. These pistons are ideal for both street and strip applications, providing a reliable foundation for increased displacement and optimized compression.

Manufactured from a high-silicon hypereutectic aluminum alloy, these pistons offer superior thermal expansion control and strength compared to standard cast alternatives. The flat top design features -8cc valve reliefs, ensuring adequate clearance for performance camshaft profiles while maximizing combustion efficiency. Precision machining includes 5/64-inch top and second ring grooves along with a 3/16-inch oil ring groove for consistent oil control and cylinder sealing under heavy loads.

This set of eight pistons is an excellent choice for builders seeking a durable, cost-effective solution that outperforms basic replacement parts. When investing in this piston set for your next engine project, you are choosing components that bridge the gap between stock performance and full-race forged pistons, making them suitable for a variety of performance applications.
