I set my reg up to have about 3psi at 1300 rpm wich puts it at about 9 wot. Not sure about your carb but a holley seat will only hold about 9psi. You ket it higher then that and wene ya let off in the corner it car overflow the bowls and cause the motor to hydro lock and bang!!!! That is why most motors go in the corners or so an old wise man told me.

You will also want to get a good belt drive pump. Why? The mechanical ones run off that lobe on the front of the cam, this at high rpm's does not hold the inlet valve in the pump open long enough and could cause the motor to lean out from the lack of fuel, same old man said that!!!!
