When manufacturers are listing gross valve lift on their cams, are they assuming a standard rocker arm ratio of 1.5 to 1? I see that almost none of them list their lobe lift only gross lift.
 
Mopar Performance cams are listed assuming stock rocker ratios for the application. I bought a Lunati cam for my 413 and it also listed the lift based on the factory rocker ratio and also non factory ratio specs.
