I have a 67 with the orig. 327 Qjet & cast iron intake. It has a new fuel pump , new lines to the tank. I also put a kit in the carb. When you idle for a few min. or park for 10 min. when you take off it runs out of gas. AT wide open throttle it doesnt starve for gas.

I'd think the vapor lock would stop the engine while idling before even touching the gas if it's vapor lock. Don't know much about carbs but I guess it wouldn't be the carb if you went with the instructions. Maybe a float is sticking or a certain notched gasket or non notched gasket didn't make it's place in 327 stardom.
My original answer is "AT wide open throttle it doesnt starve for gas."

You might want to place a see-thru filter in the line between the pump and carb to make sure its getting fuel. The filter should be full at all times.

If this proves good, then I'd probably check float level.

I can't imagine vapor lock this time of year in Georgia. If you suspect vapor lock, wrap the fuel line between the pump and carb with tin foil and place wooden clothes pins onto it. This will dissipate heat.

My 68 LF7 (327/210HP 2BBL) used to do this on days the temperature was over 80. The single fuel line runs up the front of the block and then along the head intake manifold junction. The fuel line picks up alot of heat from the head and boils the fuel on the way to the carb. My fuel line was actually toughing the head as it ran back to the carb. Just bend your fuel line away from the head and push it forward away from the front of the block. You don't need much space, certainly 1/2" between the line and the block is more than enough space.
