what makes your prefer the clay smith cams over all the other one?
It's just a presonal preference. What really matters is being able to understand ALL the specs of the cam for the intended application. You have to realistically introduce your true RPM Useage, and compression ratio, and intended induction, THAT is where the quagmire lay. One cam is not necissarily made better than another............I personally prefer Howards Cams or Comp Cams, for example. But it all comes down to componentry, what RPM you intend to run, what C/R you have and what induction you intend to run............
Isky is a very good name, but like an old retired person.......it all depends on depends...............
