I am trying to get the cam specs without pulling the cam out.I set up a dial indicator on the pushrod side of the rocker and zeroed on the base of the cam .I turned the motor over and watched it peak at .270 .I take the .270 and X it by 1.6 the rocker to get my lift.I know it isnt accurate but it should be close.I just need to know if I am on the right track.
