I have run nitrous on alot of cars. All I do is run a mallory 140 with a return style regulator. I run -8 from the pump to the regulator and -8 back to the tank. I run -6 to the nitrous solenoid and each bowl on the carb. Set the fuel pressure at 7.0lbs and forget about it. I also have a high speed retard (besides the driver) and drop 4* for every 100hp nitrous added.
