Had a fan blade come off my '60 way back in 1970's. It went down, put a small nick in the l.h. frame rail. Vibrate you off the road.

Cutting blades shorter should have nothing to do with it coming apart. If it's coming apart, it will do it with longer blades due to the mass, short blades have less.
Use a lawn mower blade balancer once you start cutting them shorter.

Sedgewick In the olden days if you lost 1 blade you had to break off the opposite one just to get home,cause it shook so bad !

Had one come through the hood of my 69 (Not Chevy). I twisted that engine over 8K and it shot a blade right off the fan. Wish it would have gone down vs up, but it was a fun discussion every time.

I realize this is an old post but thought I would add to it In 1958 Chevrolet issued a "RED" memo warning not to rev the 348 with three dueces while sitting still for fear of a fan blade exploding. Since then I have seen two case of stove bolts launching fan blades thru the hood, both with no modifications. So it has been my practice to never stand in line with the fan when running an engine. Hope this keeps someone from getting hurt.
