    I would like some suggestions for a starting point in a fuel system.

    The car is a altered.
    Transmission is 2 speed auto.
    Engine 350 chev.
    Blower 671.
    Car is a dial your own car not a flat out competion.

    The fuel pump is an enderle 110. flows 13 USA gallons per minute.
    It currently has 8 X .055 hat nozzels.
    The pump is in my opinion to big for the engine so a pump loop needs to be run.

    any suggestions appreciated.
