Preseason run up showed some water leaking out of my head gaskets. No big deal right? Well it turns out I have a wrist pin that has been rubbing the cylinder wall for what looks like for some. Here is my question the bad block is a 140HP I have an 88HP that is in way better shape, are the 2 block interchangeable? And if not does anyone have a good rebuildable 140 laying around they don't want?
