call a marine shop

they sell a cast iron repair. I used it one a big stroke motor that needed clearance into all the water jackets.

I watched a fellow racer do the same thing and he fixed it with JB weld, it worked but I personally wouldn't do it.

If you weld it you need to re machine it

I assume this is a 400 block and getting hard to find. Has is been bored yet? If not I would fill the block with HARD BLOCK, don't fill it all the way.....knock out the soft plugs and fill to the bottom of the plugs..... then bore and hone with torque plates. You will NOT have a heat problem, all the heat is on top the pistons and only the skirts of the pistons get this far down the cylinder...... We have a block that is set-up this way...... aluminum rods that swing into the water everywhere....and only 2 or 3 bolts on each pan rail.....
