Block repair; crack in the area of water jackets

[hemi68charger]

Hey gang..
Looking for some guidance and/or experience with repairing a block. I have a friend with a true survivor '68 Charger R/T 440 4-speed. Recently, he was chasing a pesky coolant leak. Well, turned out it wasn't freeze plugs, it was a crack, two of them, in the block over the water jackets. I've heard of people over the years repairing blocks, even so much as holes from a thrown rod on 426 Hemi blocks. Sooooo, what technology or techniques are out there for such repair? It would be a shame to not be able to save the original block. He's in the Central Colorado area, so Denver and/or Grand Junction would be nice if anyone's out there. If not, at least let us know the technique..

Thanks..
Troy

basically drill & stitch , drill at each end of the crack so it cannot go further & thread in plugs along the crack , you can weld also but the block needs to be heated up before welding it , you need a high nickle rod the weld it . the block can be asaved for sure , my machinist saved numbers of them
