It was definitely from a lack of oil issue....

Bad pump, restriction of oil flow or pressure/volume

Small blocks are pretty trouble free generally in this area.

A small Plug down inside a passage under the rear cap....front and rear cam plugs.....cam bearings...…things to check...

If the crank was ground it is a MUST to run a brush thru all the oil holes....and wash it real good...….

Seen guys take a fresh ground crank out of the box and just install it.

Over full oil pan could have caused the oil to aerate from windage.....but that's a stretch.....
