I'll be d**med, I thought I was the only one to see this. Mine came out of a boat that didn't get drained, cracked on both sides worse than that. I considered stiching it back together, but I found a guy that said he could weld it better than new. He used a very interesting process. He poured his own arc rod out of used 010 high nickel small blocks, then put the block in a (very) large kiln used to cure clay sewer pipes. once the block was hot, he would lay down a bead in the "v" of the crack (he ground it out previously) with his homemade rod. He repeated the heating and welding steps until he was satisfied. I took it home, ground it down and then bolted on the intake and a new set of headgaskets. I capped all the coolant outlets and filled it with solvent, then applied 30 psi of air to it through a set of block-off plates with tire valves in 'em on the waterpump outlets. No leaks! The best part was the block and heads were dead straight, I didn't have to deck or mill any of it. I was able to save an otherwise perfect 'QB' block. Worked for me.

I did put some JB weld over the rest of the pins and will paint later
