Chevy 90-Degree V6  |  Camshafts and Camshaft Kits
  

A camshaft is the "brain" that controls the flow of fuel and air through an engine. The camshaft's lift, duration, and overlap strongly affect an engine's idle quality, power curve, and rpm potential. GM Performance Parts offers a wide variety of marine and high-performance camshafts for V6/90-degree Chevrolets. The accompanying specification chart summarizes the vital statistics for Chevy V6/90-degree camshafts.
