Mech Fuel Pump Drag Racing 318

Should clarify few things. By drag racing the car I mean street/sportsman class. It's not a tight competition class. I'm possibly thinking about exhaust mufflers and drive car around in the future so mechanical pump is alot quieter than electric. I think I'll try stock pump and just see how she does and go from there. The car was upgraded to 8an fuel line and iirc that is 1/2".
