I was wondering what kind of pressures and flow rates the stock fuel pump has?

Thanks,

I believe the stock pump is 190 lph rated at 43 psi.

 

is the lph liters per hour or is that a typo and supposed to be gph?

Thanks,

liters per hour

 

Liters is what all the fuel pumps I have seen are rated in.

 

One of the b-body guys actually measured his flow in the car, not sure if it is the same exact pump but it very possibly is.
He got 147lph(38.8gph) at 43.5psi, don't know how old the pump was. The low number could be caused by the restriction of the plumbing besides the 43.5 at the regulator and by the addition of the in tank sock and fuel filter in the stock lines. Also consider a stock pump is likely OLD and should not be trusted to perform to new specs. Also factory wiring often leads to signifigant voltage drop causing low flow, Racetronix makes some nice plug and play wiring upgrades for this.
