Product Details

The Keith Black KB203-070 hypereutectic piston set is engineered specifically for Chevrolet 454 cubic inch big block engines with 6.135-inch connecting rods. Keith Black Performance Pistons are manufactured using a high-silicon aluminum alloy that provides superior strength and wear resistance compared to standard cast pistons.

Key Features:

  • Hypereutectic aluminum construction for enhanced durability and heat resistance
  • Designed for Chevy 454 big block engines
  • Compatible with 6.135-inch connecting rod length
  • Precision-machined ring grooves for optimal seal and compression
  • Low-expansion alloy reduces piston-to-wall clearance requirements
  • Improved scuff resistance for longer engine life

Keith Black hypereutectic pistons offer an excellent balance of performance and value for street and mild performance applications. The high-silicon content provides a harder, more stable piston that withstands higher temperatures while maintaining tighter tolerances throughout the engine's operating range.
