Description
If you’re building a high-compression small block Chevy that demands reliability under sustained load, you need pistons engineered for real-world durability—not marketing promises. The KB156.040 delivers the compression ratio you’re after while the hypereutectic construction resists detonation and thermal stress that would compromise standard cast pistons. This is the complete 8-piston set your engine rebuild requires to run strong and consistent.
