Horsepower limit for out of the box Edelbrock RPM heads

Hey that's really good for a teener. Care to elaborate? Like weight, elevation and Scr/cam maybe?
Cars weight around 2900 w/o driver, track elevation is around 200 ft, pump gas, cam is under .500 lift, car has gone 11.71 in 1/4 the white Duster you see in avatar.
