Well, I just broke my 360 block. Terminal?

I looked at the plug I tried to drive in, and it's deformed. Wasn't me, my brass drift was down in the plug. There's a noticeable bump at the top of the picture. I'm guessing I clocked it just right to point into the bearing saddle, not so sure I had the wrong size so I'm going to try a 9/16 and see. Even if the block goes back to the shop, the plug can stay in as far as I care.20161028_132725.jpg Or, now that I've had time to think about it, maybe the plug deformed when the wall blew out. Dunno.
