The way I see it the rod will do a lot of damage with the first rotation, long before it pokes a hole in the block. First it will strike the bottom of the cylinder bore making the reuse of the block questionable, then it will spin and break away the web on the main girdle. At a minimum wouldn't the block need to come out to properly do the machine work related to replacing the main caps?
The other things that will see quick damage is the oil nozzle and the BS.
I don't know, maybe someone else has been this lucky and could weigh in here, but my motor seized when the rod bolts broke and the connecting rod end wedged between the crank throw and the block.
