Working with a group of guys in a car club(not naming) on a ford 300 6 cylinder engine after we had put much$$$$ into it "Bill" got pissed because he was raching a new plug in and it broke so whats he do. He takes a 4 lb. small mall and actually drives the plug into the block. You cannot even see it. Can't wait to see what the inside looks like."Bill" has already said he will pay for a new block if needed which I'm sure will need. Hows that for stupidity????????
