<VV> Broken Crank!

[David O'Neal]

Sorry for the lack of the vital details.
 
This is a '65 Coupe 110 PG with a harmonic damper!  I think the mileage is
fairly low, <120k (speedo broke at 74k).  When I removed the engine I could
tell it has been removed before.  The car sat for 10+ years in a driveway
before I got it - but it turned over easily and I carefully lubed it up,
tuned it up, and cleaned it out (gas tank, carbs, etc.) before cranking it.
I expected to find something internal, such as a dropped valve seat, but the
only thing I found was a dead coil and very old wires, etc.  I fixed the oil
leaks, reworked the brakes and it ran very good until this happened.  Total
mileage I put on it is <500miles.  It did a tiny bit of visible smoke at
start up but you can see the blow-by carbon inside the block (don't know if
this amount is normal)- it probably got a re-ring job in the past.

Finally got into the engine and see what I found.

Notice the large hole milled out by Uncle Chevy to balance the crank.  There
is an even larger hole on the other end.  Those holes are large enough to
put your index finger in.

This engine still ran after the break.
