This complete kit features a hydraulic flat tappet camshaft with 212?/212? advertised duration and .420"/.420" lift, designed to provide a noticeable increase in mid-range torque and horsepower while maintaining excellent street manners and idle quality.

Key Features:

  • Valve lift of .420" intake and exhaust (with 1.6:1 rocker ratio)
  • Designed specifically for Oldsmobile 260, 307, 350, 403, 425, and 455 cubic inch V8 engines
