SBC HVP oil pump, low pressure

ok, ive built engines for years, but i have my own problems with a new motor i put together recently. the oil pump i have in my 350 4 bolt is supposed to be a hi volume pump but only puts out about 35-40 lbs when cold and is terrifyingly low when warmed up, only about 15-20 lbs.
my inline 6 has a hi volume pump in it and has 75 lbs when cold and 35-40 when warm. what am i missing here? do i have a bad pump or what? do they even sell a hi pressure pump and hi volume? and what kind of psi difference should i be seeing? i dont want to hurt this motor., and i dont have the money to go back into it if i kill it. thx for the help
