no gap on #8 plug!
 

must have impacted a piston at high rpm?

i don't know how else it could have happened, but while racing a firehawk ws6 and a z28 with paper dealer plants (and heads, she said. prolly nitrous, too.) power suddenly got very uneven, one cylinder was misfiring. i figured it was a good enough time to check the plugs and pray that i didn't have a blown head gasket. now i don't know. If the piston cracked, with my supercharged engine, it could be catastrophic if it failed under full load...

any ideas?

1998 supercharged cobra

the plugs aren't what i've seen recommended here, either.
they are motorcraft platinum awsf 32e

is that the stock plug?

thanks!

Holy Spark Plug Batman!!!

Wow, I don't think I've ever seen that happen on a modular engine...

I'd go ahead and change your plugs and take it easy on the engine for a while and see how she reacts...

To be honest, the only way I know of to check the piston is to inspect the piston.... I don't know if a compression test would show anything conclusive...

Sorry for the rotten luck Snakeman...
