The cams are variable 0-38 degree advance over the entire rpm band and can be reprogrammed via stock ECU reflash or using a standalone cam controller like the Haltech. Lift is fixed based on cam specs.
As I recall, the stock ECU intake cam timing map has 0 degrees advance (full retard) at idle, ramps up to max advance in the midrange and then tapers back towards full retard at redline.
