460 Ford back fire?

The motor runs fine at WOT, but as soon as I back off the throttle there is a misfire. Only at Half open throttle.

Sounds like cam related

Do you mean cam timing? I know it is a Comp Cam stage 1. Can it be carb related as well?

Carbs don't backfire the workings of the engine sound back thru the carb. EX a pop thru the carb usually notes a Intake malfuntion, cam, valves, etc.
