Kevin ... Perhaps I misstated ... Its not a hole *in* the block. It's about a 2 inch square hole *through* the block, beneath the water jacket and between cylinders 2 and 3. It allows the spark advance linkage to pass through from the distributor to the base of the steering column.

See the photo below -- I took a chance and lifted the parts engine this way.
