Good morning History, my godness!

History, is your welder a specialist in such large blocks? Have you been told that the ends of the crack need to be drilled thin so it can not to break any further? Was the crack course 1/4" deep and wide milled out?

The welding line must always be very short. 1 inch then 15 minutes rest so that the block is not too hot on spot. Never weld along in one piece.

There is a simple test procedure for hairline cracks, we call it Red/White-Cracktest from the spray can.

I wish you great success!

(My engine is not finished yet from the welding factory.)
