I don't have the cam disk for dyno2000 but this is a rough shot with a drag race circle track cam profile which gives the best results. I did apply your lift.

12000 somebody call the fire department and you better of been wearing a parachute :D
I guessed about duration but later I could go back and alter duration for the first two numbers you gave me. Was just taking a break between searching for back bone speacialist the insurance authorizes. Been hurting since thurday. Somebody must have the cam disks and other stuff built up already for info in their program. I sure am glad I got dyno 2000 before the newer version. Man it's expensive as all get out now.
