Info

COMP Cams Nitrous HP NX274H-13 Hydraulic Camshaft for Big Block Chevy.

Chevrolet 396-454 c.i. 8 CYL. 1965-1996. Hydraulic-High performance street with 100-150 nitrous kit or small blower. Needs 2500 stall. All COMP Cams Camshafts are manufactured to the strictest tolerances. Rigorously tested and checked for quality.

  • Wider lobe separation & added exhaust duration from base XE series help shift the power to higher RPM to allow use in nitrous applications
  • Early exhaust opening helps scavenge the extra spent gasses from nitrous or forced induction
  • Better time slips for nitrous passes at the strip
Some parts are not legal for use in California or other states with similar laws/regulations
