ENGINE
HOT CAMS
  • High-performance racing camshafts
  • Gold Series camshafts are designed to provide extra torque and horsepower; these camshafts require the use of stiffer valve springs
  • Select cams feature Hot Cams Improved Throttle Design (ITR) technology; these cams improve throttle response throughout the entire rpm range
  • while providing excellent power gains through the mid-range and top-end
  • Builder Series camshafts were developed for engine builders that have specific requirements to maximize their particular engine configuration; see
  • notes in the performance description for use with OE valve springs or the requirement of stiffer valve springs
