I bought a street 327 short block from a guy who said it was rebuilt and always used oil even after he rerung it.The first thing i noticed on taking it apart is that the bore was .020 over, but the pistons were not marked as such.I measured the pistons,and they are .020 over but the top and second ring gaps are way over .100.Could they have stuck a set of standard rings in a .020 block?They probably looked at the pistons and thought they were standard.
