454 engine surges @ idle

My engine barely idles and sometimes gets a boost surge like a plug wire is loose or something but all are tight on plugs and HEI cap they are new Taylor wires. When I rev up the motor it runs fine but when it calms down to idle it sarts running rough again.
It also has a Edelbrock #1407 750cfm carb.

Any ideas would be good!
