    Here is how it reads just so you see what I am seeing:

    These Specs are for cam installed @ 107.0 intake center line

    Duration @ .050 Intake 226 Exhaust 234
    Lobe Lift .3200 .3320
    Lobe separation 111.0
    post #37 i showed what lift would be with a 1.5 rocker or a 1.6 it is the rocker that add to cam lobe lift the cam has a lobe lift of .320 x by 1.5 or 1.6 what ever rocker Ratio must be added to cam lobe lift
