Thanks for all the responses. I have done several things so far. I took the engine off that POS stand and built my own. Not on wheels but I don't expect it to be there to much longer. This new stand is suitable for moving with a fork truck. Even put extra crossmembers under the oil pan so that no one can dent it with forks. Monday I'm loading onto a van and taking it to a professional welding shop. I showed him the same pictures and he did not think it would be a problem to fix. His shop was repairing a cast iron pump housing while I was there. Does cast iron all the time. Interesting - he asked me what it was for and I told him a 78 Corvette. Turns out he has a '55 and currently doing a frame off rebuild on a '66.

Brazing on a casting the size of an engine block can be challenging. The metal needs to be cooled at a constant rate, like in an oven. I've had exhaust manifolds brazed and the welder used the oven for hours in his wife's kitchen. That cost extra to keep the wife happy.

TIG with a high nickle rod, preheat and post heat-done. E-Z. I keep a few rods in the shop for such repairs, they cost about $9 ea.

A welder who is also a corvette guy, it sounds like you found the right shop. Good luck with the repair.

Interesting this thread is going. My machine shop found a small crack in the starter bolt ear on my SBC. It's there being welded right now.

YUP. That is exactly the way to do it.

Picked up my block yesterday, charged $80 for the weld.

Weld it and forget it. We heat that sucker up red with a torch Then hit it inside and out with that (I forgot what brand it is) cast iron rod. Low nickel.
Want it to be malleable. Don't worry. It cracked in a really low priority area. There is no oil pressure there. Splash at the most. Seem all SBC fuel pumps leak oil here.......
No worry's love..................
