.007 on the pistons is ok, loose and mabye noisey when started cold, but ok. .012 on the top ring is bad, and technically, leaving the 2nd ring a little bigger than the top will help ring seal. So with a 360 (4.03 when bored .030 over) I'd be setting the top ring at .017 and the 2nd ring at .020. Also, always round up when you get a "point something" (4.03x.004= .01612, or .017). You want to err to the large side on any performance engine.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
