With TDC verified and a lifter on the cam, another dial indicator on a magnetic base can be used to degree the cam. Checking duration at .050-inch lift as well as maximum lift is easy with this setup. Also, using the same "before and after" technique as finding TDC, we can find the actual point of highest lift, known as the lobe centerline. Adding the intake centerline (ICL) plus the exhaust centerline (ECL), then dividing by two gives the lobe separation angle (LSA).
