Thanks to all for your responses. It seems the short answer is to use cam connections with lift off enabled. I used this and it worked as I had hoped.
I used Autoselect for cam face #1
I used Autoselect for cam face #2
I set the coefficient of restitution (e) value to 0 which is the min and to 1 which is the max and the response was identical. It worked in both cases. This value apparently only effects the analysis, not the motion.
If you select Enable Liftoff on the Cam-Follower Connection Definition dialog box, the two cams are allowed to separate and collide during a dragging operation or an analysis run. The cams do not interpenetrate if they collide. If you enable liftoff, you can also define a coefficient of restitution for your cam-follower connection. This value determines the energy loss due to the impact when cams collide after separating.
Petter also points out below that there is some additional functionality that is available on WF 5.0 that will also be helpful. Thanks again everyone for your help,
