    Carbureted 4.3L question

    I have a 4.3L engine with an Edelbrock 1403 500cfm carb. My issue is around 3k rpm under load and medium to heavy throttle the engine wants to kick out. It has a new distributor, wires, plugs and timing set to 0. With no load the issue doesn't exist. I have changed rods and springs to test leaner and richer sets. All changes don't seem to make any difference. I'm running out of ideas. Any advice?
