Crane Cam F-288/4134-6

In the past I have always measured .050 on both sides of max lift of the intake lobe to degree my cam. Using that method this cam is in the motor at 108 ATDC. The Crane specs on the cam call for an intake opening number of 42 degrees BTDC and closing 66 degrees ABDC (measured .050 off the base circle). Using this method I get a reading of 114 ATDC for the center of the intake profile. My gut tells me to use my old method and install it at 102.
