Yeah, I guess that did come out fairly bad. But it's possible, but most blocks over time get scored from one thing or another. As you know, this is why when rebuilding, we at the very least hone the cylander walls, if not bore.
And with you switching the wires... can do it again and take a picture I'd like to see it ;-P
But seriously, you didn't do any damage. The worst you may have done was have a little extra gas build up in the combustion chamber so she she fired up that first combustion was rich... not going to kill your engine. One of the ways to test a spark plug is to take it out ground it and turn the car over. You did no more damage than this test... which is nothing.
