Sickening- Cracked Block - Repairable?

[65CopCar]

Well... The company Lock and Stitch is just down the road from me, for years they have sold their repair kits & repaired equipment at their facility while also having a crew that travels worldwide repairing cracks on heavy equipment, ships & anything else where the owners were willing to pay the costs... But it looks like in 2025 the company was acquired by Wärtsilä & the new owners aren't selling the repair kits anymore... I had heard something about it earlier this year but now searches appear to confirm that.. Other companies are selling the original design pins, the drill guides don't appear to be available... Though honestly that wouldn't be hard to fabricate..

I had also heard that they were not selling the kits anymore.

Goodson seems to have them and they say they have the installation tools also.

I still have a 440 I rebuilt in the early 80s. I found a similar crack in it. I veed out the crack with a grinder and filled it with JB Weld. I hasn't leaked in decades now.

Back when I was dead broke in the late 70's I did this same repair. A 64 Fairlane wagon with a straight six and a cracked block running up the side to the deck. Wire wheeled off the paint and glopped it up with JB. It held fine and didn't leak for three years till I sold the car.
