Hey I have this friend that bought Kent cams, cam gears, and belt from Focus Sport. It costed over 800 dollars brand new. He wants to sell them to me brand new in box for 300 dollars. Considering I don't ever drive that fast, but would like to put some power in the Focus. Is it worth it even though I don't really need the power? But it is such great deal. But then it will cost 200 for instalation and dyno. What do you guys think?
