1993 Chevy c1500 350 Piston Slap/Rod Knock

I bought a 1993 Chevy Silverado a couple of weeks ago, it has a rebuilt 350. I've experienced a knocking like sound coming from the engine, but I'm not quite sure what it is. (Truck was running cold in the video) I know for sure that the timing needs an adjustment, but I wouldn't think that bad timing would cause this knocking. The knocking can't really be heard from inside the cab.    The truck is hard to start at times but it'll go. It tries to die when you come to a stop and i'm always left applying break and gas to keep it going.
I need some help identifying what the cause of this knocking is and how to fix it. Thanks guys!

UPDATE: I drove the truck today and sounded even worse, kind of like a fork in a blender. After the drive, it didn't seem as bad (at idle) but you could still hear it when you lifted the hood
