Trying to troubleshoot a problem my friend is having......has a lot of popping coming out of the carb at WOT....doesn't do it at idle or cruise speed just WOT....sounds like a popcorn machine....460 w/ Holley 750... Suggestions and ideas greatly appreciated...

Sounds like a lean condition to me.

Simple carb adjustment or does it need to be gone thru?

Pretty long list of possibilities.

Jetted lean,  low fuel volume/pressure, sucked  intake gasket/base gasket, garbage in the carburetor, low float level, poor tank ventilation, plugged pick up tube, kinked fuel line, bad fuel pump, fuel line air leak, carburetor too large and not set up correctly.

A popping at WFO means QUIT RUNNING IT WFO until you have exhausted most everything he said, or you the carb won't be the only thing you are rebuilding.
