You could put 50lbs injectors on a stock motor and when tuned right they will just barely open and then close again, but on a wild stroker making 600fwhp they need to stay open much longer to supply adequate fuel and the stock pump wont do it at least not under normal circumstances.
The stock fuel pump should be replaced if your engine actually makes enough power too need bigger injectors. If not from the flow standpoint from the age standpoint.
The stock pump can support some power when in good shape and fed sufficiant voltage(stock wiring is too small) but these are 10 year old cars.
