If I found a block that was the right build date for my '67 GTX that needed to be sleeved, I wouldn't hesitate at all about buying it. If I was just building a Hemi engine, the current block is the way to go. As to repairs, it would have to be something cosmetic like a window in the pan rail for me to consider it. Some of these blocks with cracks in the main bores or the lifter galley, I don't care if God himself did the repair, I wouldn't touch them.
