If you're heading to the great outdoors, Comp Cams offers camshafts designed specifically for marine applications where low idle speeds are necessary and where restrictive exhausts require special cams that work well against wet exhaust system back pressure. These unique camshafts generate an extremely wide powerband, offering the low-end torque needed to jerk skiers up quickly and the high-end power needed for maximum performance. Also, Comp's larger camshafts are engineered for engines with less restrictive exhausts and drives that will tolerate higher idle speeds. An excellent choice for jet boats or power boats.

Features:
  • Extremely wide powerband helps get boat on plane while making maximum horsepower
  • Work against exhaust systems with restrictive back pressure
  • Power enhancement helps maintain top end speed for long distances
  • Intended for applications where low idle speeds are required

  • Can i use this Cam with the factory fuel injection? 1996 k2500 pick up, motor is in a 67 chevelle with no emission hardware anymore And what other supporting hardware will I need? IE- Valve springs

    Asked by: ABrock
    This is a jet boat marine camshaft, it is not designed to work with this factory fuel injection. You will also need an upgraded valve spring.
