### ⭐⭐⭐ 







  
  
    Idle sounds nice, good chop
  

*by D***N on Reviewed in the United States 🇺🇸 on December 21, 2017*

Standard quality comp cam. Ground on a smaller base circle, will require longer pushrods. Came with a generic cam card as opposed to a Cam Doctor printout. Idle sounds nice, good chop, and is stable and easy to tune. However, that is about all this cam is good for- it made 380whp in a 11:1 compression LS1 with Fast92/92, 100mm MAF, aftermarket PRC 225 heads, 1 7/8 headers, and all supporting mods.
