No problem with patching up a block if it is a fairly useless area. One of
my employers who used to race drag cars tells stories of trying to find the
blown out pieces of grenaded race engines, so the local welder guy could
patch the block back up. Imagine scouring the 1/4 mile at 3 am with a
flashlight looking for dime sized pieces of engine block. Supposedly the
more pieces they had, the cheaper the repair was. They would always end up
fixing the side of the block as the rods would grenade at high rpms and I
believe the water jackets in those blocks were almost completely filled with
hardening stuff to stiffen them, so I doubt that a normal engine would
withstand such a problem and be salvageable, but if the break is not
structural (IE thin area, non load bearing area) it can probably be repaired
adequately, provided the block has not been extensively damaged.
Any competent welder (make that a very competent one ) can weld cast iron.
It's not impossible, but it does take a lot of patience and skill. I'm a
long way from mastering the skill, but I've messed around with it a bit and
it's doable. I read that the Aardvark has a spare mill ready to go, but you
might be able to salvage the other block. Otherwise, the block would make
for an interesting coffee table support.
