A faster intake valve opening increases engine vacuum and enhances throttle response. Special intake closing ramps close the valve sooner, providing more cylinder pressure and torque without resulting in excessive valve train noise. Faster ramps achieve maximum velocity sooner, increasing the area under the lift curve and providing maximum horsepower. Smoother exhaust designs allow for a more effective purge of spent gasses from the combustion chamber to further increase horsepower.\u0026lt;\/li\u0026gt;\u0026lt;li\u0026gt;For Carb or Tunable Fuel Injection3\u0026lt;\/li\u0026gt;\u0026lt;\/ul\u0026gt; 1: Cams for '55-'57 engines can be custom ordered. 2: The '87+ Chevy Small Block received provisions for Roller lifters.
