What size carb ?

I wonder what point they would run out of fuel in a dragrace situation? Right about the time my brothers 70 383 Cornet would start gaining and pass me in my 69-340 Swinger.
At least change the fuel line from the pickup to the pump to a 3/8" relatively straight non-90*. that will help substantially - change the picjup to 3/8" when you can.
