Engine Making Noise Happens always Always

Q:  I just rebulit my 350 Chevy motor. When I start it, a rattle sound comes from the engine. It sounds like a lifter sound.

I thought maybe I had a bad lifter or 2 so I replaced all of them to be sure. The sound stayed the same.

I then was told that maybe I had a bad grind on my cam so I replaced it. Same sound.

I replaced the rocker arms, same sound. I then purchased a stethoscope and found the noise to be comming from the cylinder wall and at the top by the head.

Could it possibly be that I have a piston slap? It's most noticable on the number 7 cylinder. I even went as far as to check the oil pump.

The noise can be heard from the transmission bell housing and also at the top of the intake manifold.

With the prod on the center of the manifold or on the bellhousing it sounds like a clicking sound. I just find it hard to believe that a freshly bored engine can have a piston slap. Any help or guidance would be appriaciated.
