What brand of pump do you have? A q-jet is notorious for being hard to keep supplied with fuel. When I built my car it had a 780 Holley and I was using a Mallory 140 pump and a 3/8 fuel line from the tank to the regulator and everything worked great. When I switched to a q-jet combination I ended up switching to a Barry Grant 280 pump and a 1/2 inch line from the tank to the regulator to get it to run right. The amount of fuel to a q-jet is critical.
