Thanks John, its all good shop talk.

As for that cam, I'd need the .006/.004 numbers, and the ICL. The ICL and LSA, will dictate what the exhaust timing events are. In otherwords, a 111LSA cam,...

This particular program, does not. I do have a more advanced program, that can sort of simulate changes in velocities based on valve diameter, throat diameter, CSA, and so on. Thats really for head...

Crane 651 cam. 880HP at 6000 RPM....
