Many of our competitors list their cam specs based off of a 1.65 or 1.70 rocker ratio. What this typically does is inflate the cam specs to make their cams appear larger than our grinds when in fact they may not be. In all actuality, our 530 lift camshaft can actually be larger than our competitors 560 lift camshaft.
