Stan, apparently Dave Bisschop has a revised version of the Old Faithful hydraulic roller cam known as OF2.0 as mentioned here by ta man.

That specific cam is shipped without a cam card and with limited specifications provided to the customer. But as expected information has reached the internet and has been posted. I believe it uses Comp XE lobe 3196B on the intake and Comp Magnum High Lift lobe 3123B on the exhaust. As usual the cam is custom ground with a 112 lobe separation.

Due take note as with all Comp lobes ordered with a "B" suffix code the actual numbers can, but not always, vary slightly from the listings in the Comp catalog. The .050" duration remains the same but the .006" duration can vary by 1 degree, possibly by 2 degrees. And the lobe lift will typically be increased by 0.001".
