[89 Cobra LX]

Below are some of the specs for my cam. Can someone tell me how my motor should be behaving? I have some good lift #s, but the duration #s look a little low. Does the low duration mean my power band will be lower in the RPM range? I recently dyno'd my car and the peak HP occured at 4500RPM.

Lift
Intake .499
Exhaust .510

Duration
Intake 275
Exhuast 279

Thanks
