Also known as a Chev Big Block the oil filter lives on the left side of the oil pan at the rear of the oil pan.
I don't know how different an '81 is from an '82, but on the '82 there was a peice underneath the engine with air fins that can be unbolted. That peice holds the oil filter.
The oil filter housing is located on the front of the engine cases. It has a single bolt that attaches the housing to the engine. The housing itself is finned for cooling.
It actually holds 3.8 quarts. If you are changing the oil: with filter change: 3.3 quarts without: 3.2 quarts
