OIL LEAKAGE WHILE DRIVING FORD LEAKS OIL  1971 ford 302.  There is a hole in the block on the left side (as looking at the engine from front of car) just above and ahead of the motor mount.  It appears to have been machined since it is perfectly round and un-threaded.

If an oil leak is not obvious, clean the engine with a strong detergent before further inspection to make detection more accurate. Always clean an engine cold to avoid steam which can cause problems inside electrical connectors. Use a flash light to pin point the source of the leak, then formulate a plan to repair it which can vary greatly in effort, it's best to get a second opinion if a major repair is imamate. When inspecting for leaks start at the top of the engine and work down as oil can travel a distance before collecting into a drip.
