<VV> Broken Crank!

[Doug Mackintosh]

If that is #1 throw on the short end of the break, it looks almost identical to what happened to my first Corvair many years back (except it did not break across a balance hole). Mine was broken for a couple weeks before I got around to fixing it. On the drag strip the short end of the crank would tip up enough to throw the belt when I dropped the clutch, giving me a few extra HP for the run.

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.
