IMO welding cast iron is not the best method for novice welders........welding cast iron is tricky and will make a veteran welder cuss up a storm..........I would recommend you repair with the epoxy of your choosing, if the repair is not successful its not a big deal to have a do over.....

Prep work is of huge importance when it comes to repairing with epoxy...... If you spend the time necessary to prep the area all should be ok.

I second this, welding cast iron is tricky for the Pro's, not advised for amateurs.

JustJason....."drill and pin the block"......more info please.

Where the very ends of the cracks are. Drill them to 1/8th just to make sure you are at the end of the crack. And then drill to 1/4 inch or 5/16th, you'll have to look and see what works best for you, as this depends on the size of the crack. After that, tap your holes accordingly. After your all prepped, start your patch (JB weld is fine). And when you get close to the holes, coat a couple of short bolts with JB weld and thread them in. You don't have to "torque" them down. Just thread them in until they more or less bottom out. This will help keep the crack from spreading. Use either stainless or grade 8 bolts.

I had a crack in the same spot on the block, not quite as long. We had lots of really cold days and nights here in Ga during this past winter,

the walls are thin there because the water jacket. I thought I only had a crack on the outside, and not on the internal side, but I was wrong . It took me months to find this out. I did a dye test , and sure enough water was getting through the internal crack on the back side. I hope you dodged a bullet too
