A follow up to "oil starvation issues" thread

So I started pulling the engine down , pulled pan and its full of bearing material. One by one the rod bearings looked like they were getting restricted oil flow but not as bad as I 've seen. The rods looked fine.

The main bearings on the other hand WERE COMPLETELY DESTROYED

, to the point of the 3 center main caps getting "blued or blackened" .
As you can imagine I'm angry , pissed and any other verb you can come up with.
This isn't my first small block , to say the least...............but it IS my first Dart block ( Little M sportsman ).
The main caps no longer fit tight in the registers either, BTW.
Now here's the really pathetic part.........THESE BLOCKS ARE SUPPOSED TO BE PRIORITY MAIN OILING? WTH is going on here?

Main clearance at .003 , crank is straight ( BRC crank ) new Melling pump etc etc. The plugs in the block at rear are not plugging any passages...not that I'm aware of. The sump had 6 quarts.

Now how in the he*lL can a priority main oiling block starve the mains?

You can bet I'll be calling Dart in the AM.
