Product Details

The COMP Cams 20-743-9 Xtreme Energy mechanical roller camshaft is engineered for mild street/strip performance in Chrysler small block 273-360 cubic inch engines. This solid roller camshaft features an aggressive lobe profile that delivers improved throttle response and increased top-end horsepower while maintaining higher engine vacuum compared to equivalent camshafts from other manufacturers.

Key Specifications:

  • Advertised Duration: 268° intake / 274° exhaust
  • Valve Lift: .552" intake / .564" exhaust
  • Lobe Separation Angle: 110 degrees
  • Camshaft Type: Mechanical (solid) roller
  • Recommended RPM Range: 2000-6000 RPM
  • Noticeable performance idle

Performance Features:

  • Quick-opening lobe profiles provide increased responsiveness and more area under the lift curve
  • Enhanced engine vacuum improves performance consistency and power brake operation
  • Ideal for 9:1 compression ratio with 2500+ RPM stall converter
  • Delivers strong mid-range to top-end power for street and strip applications

For optimal performance, COMP Cams recommends pairing this camshaft with aftermarket intake manifolds, headers, and lower gear ratios. This camshaft is designed for Chrysler small block engines from 1964-2003 and is sold as a camshaft only (lifters and valve train components sold separately).
