1990 Mustang GT:

I have this information for the 1990 Mustang GT Cam stock cam:


1989-1995 5.0L Mustang Roller Cam
Part #'s E8ZE-6250-CA or F1ZE-6250-AA
Advertised Duration: 276 / 266
Duration @ .050: 214 / 210
Lift w 1.6 rocker: 0.444 / 0.444
Lift w 1.7 rocker: 0.472 / 0.472
Lobe seperation: 115

However, does anyone know specifically when these events are supposed to occur (and at what lift ... ex. .050" etc.) because you cannot degree a cam in properly unless you know when the events are supposed to occur and compare it to what you have measured. Cam cards normally give this information but where is this information for a stock cam??? Can anyone help me out here? Thanks!
