That was interesting, I had never seen it done like that. I always welded

cracks.

I had heard of stitching cast iron before but had no idea how it was done. Might never have it done but nice to understand what it means.

This big Dodge race car transporter/Army truck being restored in England had the head crack stitched:

Thanks! That was a really good Tutorial!

I would think drilling that first hole at the end of the crack to start the proceedure would be the most important hole drilled, because one would need to position the hole so as to be sure it would circumvent any further cracking. After that it looks like - if your patient - it would be fun to do. I personally would not use Tap Bits in a drill, I would hand Tap every hole, thats only because I did some Machinist work in the 70's and wouldn't want to rush the Taping Stage. Well Thanks again for Sharing that - now any one knows they can Fix a Crack in their Block without welding.
