396/402bbc- internal/external balance ?

My beautiful machine is out again- rod bearing on #5keeps going.
Rebuilder replaced crank, bearings, rods twice. He said this motor is internally balanced, but others have told me it could be either, and others still have told me all bigblocks were external. rebuilder has no explanation for bearing wipeout. ANY INFO GREATLY APPRECIATED. I want my truck back!
