Cracked engine block repair question?

[Blackpowder44 (RIP)]

I have to say again, DO NOT WELD, your cast block is 70 odd years old, if you heat the block up to the temperature required to weld up the crack it will have an adverse effect on the steel on either side of the crack and when the weld cools down it will contract only very slightly nbut this can cause the metal on either side of the crack to itsself crack in time.The stiching method causes no stress to the surrounding metal, can be finished off with a flapper disc and once painted, no sign of the crack. Great scab of welding or brasing looks like shyte and if as you say your enging is a really good one why ruin it by welding. I know this sounds like a rant, but in the last 40 years I have seen too many engines with this scabs of welding. Also you have to pay someone to do the welding whereas you can stich the block yourself. HAVE NOTHING TO DO WITH WELDING OR ANY CRAP PUT INTO THE WATER TO BLOCK UP THE CRACK,please take on board what I have said, good luck, John.
