Not sure where it's damaged but can it be sleeved? Or is this on the deck?

A welding shop with a oven can do it... they will use high nickle rod when the block is good and warm then let it slowly cool back in the oven

I've had that happened on a 440 block, call around to the heavy duty Deisel repair shops in your area and get the name and contact information on the welding shop they use to weld cast iron I ended up on my block having the deck surface brazed by a cast iron deisel welding shop then I had two sleeves installed and then had to have the block decked on a wet surface grinder. The head was cast iron welded and I had to find a shop that had a wet grinder to surface the head also, the regular automotive machine shops in SO CA said they wouldn't touch a welded head on thier equiptment because cast iron turns into a really hard material(it would damage the cutters on thier rotary broaches) when welded Good luck, let us know what you do and the shop that does the work for you please
^^^^^^^this, i have a block that was reapiered this way

It is indeed on the deck. The damage is like a crease joining two cylinders

That looks exactly like my sons did. Simple fix with tig or high nickle stick rod.

Can you give me the number of the nickle rod you used? Previous owner got wild with valve notches and got to close to pushrod holes, trying to find a fix.

The last two that I repaired I tigged. My stick welding skills are slowly eroding since I retired from Millwright work 3 years ago. In my shop I either grab the mig or tig. Check out this link if you are going with stick. I used a 3/32 rod. Like Bob said protect surrounding areas from splatter. I use fiberglass cloth and a product called kayo-wool. Keep covered to let it cool slowly after the repair is done. Some guys want to make a simple repair into a project. http://www.messerwelding.com/Product%20PDFs/by%20part/MG%20765.pdf

With the new welding materials and methods this is an easy fix.Just make sure the person doing it is experienced.Protect the area near from any weld splatter. We do this type of repair quite often.

Thanks!
Would you know about the MG200 electrode ? Would it also do the trick and not be as hard to machine later on ?
