  • Engineered specifically for oval track racing performance
  • Compatible with Chevrolet Big Block 396, 402, 427, and 454 engines

Performance Benefits:

  • Optimized for sustained high-RPM operation typical in circle track racing
  • Aggressive profile provides strong mid-range to top-end power
