The article says they are proprietary. It does say that lift is over .600, duration @ .050 is over 260 and it is on 109 centers. Idle at 1,300 rpm and torque peak at 5,800 is a big cam for the street in my book. Sounds to me like it's a good bit over 260 @ .050" if that's how it behaves. You know what I'm gonna say, but I'll say it anyway...call Dwayne! And I'd go roller.
