On a Chevy 216, most (or maybe all) of the connecting rods could be changed from the bottom without removing the cylinder head by pulling the piston down far enough in the cylinder to expose the wrist pin. It was not uncommon to find one or more undersize rods in an otherwise standard dimension engine after a damaged crank journal was reground in the block.

A pretty well-built wrench jockey could also muscle a portable boring bar like my Van Norman 944S over a fender and bore one scored cylinder oversize if it got damaged by a broken piston ring. Used car lots were bad about doing stuff like that- - - -"Just patch it up enough to sell!"
