Product Details

The COMP Cams K11-572-4 Nitrous HP K-Kit is a complete camshaft package engineered specifically for nitrous oxide applications in Chevrolet Big Block 396-454 engines. This hydraulic flat tappet camshaft features a 250/264 duration profile optimized to work with nitrous systems, delivering aggressive performance while maintaining street drivability.

Complete K-Kit Includes:

  • Hydraulic flat tappet camshaft with nitrous-specific grind
  • Hydraulic lifters matched to camshaft specifications
  • High-performance valve springs designed for increased valve train loads
  • Steel retainers for reliable valve train operation
  • Valve locks (keepers) for secure valve stem retention
  • Valve stem seals to prevent oil consumption
  • Timing chain set for precise cam timing
  • Assembly lube for proper break-in procedure
  • Installation instructions and COMP Cams decals

This camshaft kit is designed for big block Chevy engines using nitrous oxide injection, where the unique duration split and lobe profiles help maximize power under spray while maintaining good cylinder pressure. The hydraulic flat tappet design provides quiet operation and eliminates the need for valve lash adjustments. Everything needed for a complete camshaft swap is included in one convenient package.
