COMP Cams has awakened the musclecar sound--and it's nastier than ever! Introducing Thumpr Series cam and lifter kits

Features:

  • Great sound (early exhaust opening and more overlap)
  • Great power (new lobe designs give great area and air flow)
  • Great mid-range response (early intake closing traps more air)
  • Minimal engine vacuum - requires mods for any vacuum accessories such as power brakes
  • Designed for use only with valve train upgrades including COMP Cams® Beehive™ Valve Springs and roller rockers
  • Works best with looser converters, more rear end gear and other performance engine modifications
