cams lift lift refers to maximum valve lift this is how much the valve is lifted off its seat at the cam lobe s highest point valve train how is it measured valve lift is the amount usually in inches that the valve is lifted off of its seat it is usually measured with a dial indicator at the tip of the valve lobe lift is the amount usually in inches that the cam lobe increases in radius above the cam base circle tip to quickly find maximum lobe lift measure the base circle of the cam and subtract it from the thickness across the cam lobe s highest point see the diagram below tip maximum valve lift can be calculated by multiplying the maximum lobe lift times the rocker ratio for example a 0.310 lobe lift cam yields 0.496 of valve lift when using a 1.6 ratio rocker arm formula valve lift lobe lift x rocker ratio base circle and lobe lift pistons base circle lobe lift base circle and lobe lift base circle rods what does it do the intake and exhaust valves need to open to let air/f
