After my cracked 4122 block was sitting in the basement here for over 34 years my son and I got it out last weekend. I have decided to try and weld the darn thing since it's not worth much. Most of the places I called want over 5K to weld it then it would need to be machined also. I am either going with Muggy Weld 77 rod or I will do Belzona Super Metal, this is some good stuff. Since these are outside water jacket cracks my feeling is that the exhaust manifolds which are really close to that part of the block may cause problems with the Belzona. The epoxy really looks good and would hold IMO, but I think it would need a heat shield of some sort behind the manifolds. What have others done on this? I cannot afford a ton of money to fix it and like I said I am not out anything nor is the block worth a lot right now. Most I had in the engine when I bought it was $500, the 583 heads, intake and hi-po manifolds came with the engine so I don't care at this point.
