Or - Gone in 15 seconds
This is the result of
the failure of an overstressed or defective new replacement
stock exhaust valve. Others that run 351C's have had similar
experiences. The engine had seen 6000 RPM maybe 15 times
and had accumulated a total of 1445 miles since new. It
took about $3000 to recover from the failure of a $9 part
when a $12 part would have prevented the whole mess. Take
my advice - run stainless one piece valves if you can.
