Default Cam timing

Does anyone have, or know how to get, valve opening and closing specs for Mopar cams? I've checked the archives but couldn't find anything. Thanks for the help.............djs

I have a program that will figure opening/closing times using rated duration, .020" and .050". All i need is the duration and centerline.
