|CNC-Dude||Many times if there is one crack, there are more. As already stated, 350 blocks are plentiful enough not to take a chance on one that already has problems.....|

|Stroke||Dunno, if it were mine I don't think I'd bother considering those blocks are everywhere... I think I have 3 or 5 of them empty. Whenever I find a good one I try to snatch it up. Post a pic of your crack if possible. Once, in the wayback, I left a brand new sbc on a run stand full of water. Well, over the weekend heat went out and the temp was about low teens to single digit. There I was, staring at those two hunks (each side) blown out right about where you say your crack is. I'd suspect something along those lines. I can tell you one thing, cracks do not go away or get smaller. You could stitch the block, but why, given the availability?|

|DoubleVision||It depends on the depth of the crack. I seen one block with a crack from freeze plug to freeze plug on the side of the block and it never leaked a drop and it`s still being ran today. Problem is, there`s no way to know how deep the crack is. My best advice would be to have it pressure tested.|

I have an 010 block and after taking head off and oil pan I found a crack about 2 inches from left to right by the antifreeze drain plug. It is about 1/2 inch from the oil pan on the left side(facing the pulley side and 1/2 inch above the oil pan lip. It is only in the fluid journal. The guy I bought it from said it had never leaked in the 10 years he ran the motor. It was full of antifreeze and not leaking. Just wondering if I put J B Weld on the out side if it would hold if it indeed began to leak if I installed it and ran it? I could try to put it on the inside as well. I dont want to replace the block but will if I have to. What about liquid steel??
