Sparkplug issue

The other day I was driving my Chevelle when it started running rough all of the sudden. I pulled the plugs an saw that the plug from the #1 cylinder was fouled. the gap was almost completely closed and the electrode was bent off center. The engine is a 383 with RHS heads that have 67cc chambers, 2.08 intake/1.60exahust valves,KB135pistons,cam specs duration 282/292, lift .465/.485, 114 lobe separation. My question is how/why did this occur to the #1 spark plug?[IMG]P813006[/IMG] [IMG]P813003[/IMG]

All of "A" sudden. I hate when people say "all of the sudden".
Put a new plug in and see what happens. It may have been a weird one-time thing.

Thanks, I already did replace it and it seems to run fine now, but I was curious why it happened in the first place. Sorry for the grammer foo-pah

Could've been a poorly defective plug.
