Drag Race Mechanical Roller Cams
  • Made from Crane's billet steel camshaft stock
  • Greater lift with dual pattern profiles for balanced intake/exhaust flow for more low-end torque and greater upper-end horsepower.
  • Requires 11.0:1 to 12.5:1 compression ratio, and a 4500 rpm stall torque converter
  • Crane performance is built into each and every one!
