Stock fuel pump specs?

I was just wondering if anyone knew the specs on the stock fuel pump. I have done some looking around with no luck... other than having found what the fuel pressure is (or should be)... the fuel pressure for the LS1 is within a couple pounds of pressure and so I'm wondering how many gallons per hour the pump is capable of supplying... I'm sure I'll need to swap the pump out for the LS1 pump but wanted to know for sure just for the heck of it. If ya know... please post. TTYL!

The VX fuel pump specs might be hard to find.
There is a good chance that old pump will be adequate for stock LS1. Once you are done with the conversion, monitor fuel pressure under heavy acceleration or load if it drops you need bigger fuel pump. Make sure to replace fuel filter before testing.
Fuel pressure gauge is available from most parts stores.
Good luck
