Lets say I have a cam with these valve events at 0.050 lift.
IVO 1.5 BTDC
IVC 37.5 ABDC
EVO 49.5 BBDC
EVC -2.5 ATDC

Now I want to retard the cam 2 degrees, What will my new valve events be?

Actually IVO of 1.5 BTDC would change to 0.5 ATDC and EVO of 49.5 BBDC becomes 47.5 BBDC..

To the OP: probably a typo but (-) is not used in timing events.
Hmmmm... Here is a screen shot from Desktop Dyno 2000, it clearly shows a (-) number. I know people don't like DD2K
but I'm not making it up. It is there.
