I admit it sounds like a top end noise but there aren't many types of load-based engine noises and bearing/piston is the most common
I really hope it isn't for you

That would be truly disappointing. Thanks for the info though.
The pistons & wrist pins are new, and all the bearings are new, with clearances under .002".

Either way, that engine isn't staying together for too long, either because you take it apart, or it takes itself apart.

Could it be piston slap if it has 160psi+ compression though?
The noise becomes much softer & almost disappears after it warms up.
