I am trying to put it what I have been told is the stock cam for the 00+ 4.8/5.3 trucks....191/190 .457/.466 114. But these numbers don't fly with the Desktop Dyno cam calculator. I get a "A valid IVO value is required." Where IVO is intake valve opening BTDC.

Here is what it looks like. it calculates the last four grey boxes based on what is input on the first 6 white ones.

PS: hopefully this format doesn't tweak the home screen like I did last time.
