No the stock one is set to around 38psi from memory. I have just put a Holly adjustable regulator on mine to sort out fueling problems, and it does a good job. Easy to fit and adjust all the way up to 80psi from memory, although you would never be running that pressure.
Mike, adjusting the fuel pressure is only good if you need more fuel due to fairly large modifications. Unless the fuel regulator is stuffed, you probably will not see any difference using an adjustable one, although it makes fine tuning easier.
