These Small Block Ford hydraulic roller kits use a Standard Base Circle cam, NOT the weak, under performing small base circles that most retro-fit kits use. (Small base circles have increased potential for valve train control issues, especially at higher lifts and rpms.) You will have None of these problems with our standard base circle cams. Also there is no need for drilling or tapping new holes in the valley for the flimsy sheet metal retainer and the associated problems with iron chips & filings contaminating your engine.
