84 fuel pump specs
The stock 84 fuel pump how many gallons per hour can it flow? Reason I ask is the nitrous system I want to use asks how many gallons per hour it can flow at 6psi. My car is carbureted that's the reason for the low fuel pressure.

I would doubt that for an early L83 pump. I would think something in the 35GPH would be more likely. I believe that even early TPI pumps were in the 40GPH spec. That's "free-flow" spec so you might ask the NITROS people if they can calculate from that.
Some after-market resellers advertise a GPH but most don't any more.
Aside from GPH you might ask the NITOS folks about regulators.
On some systems using nitrous or even just carb there both a inlet regulator used and a return pressure regulator used to more precisely control fuel pressure.
Put a regulator on yours and do the math. Might be the real answer to supply the vendor.
The GPH will diminish based on PSI of the regulator also. Here's maybe something to be considered typical. The pump used in the chart is the Walbro "stock TPI" replacement.

Don't bother with the stock 1984 fuel pump. It is barely adequate for a stock-ish engine. If you are going to put nitrous on you will want to upgrade to a 1985+ pump.
