I had a blade on my fan just bend and tear up the radiator. Never seen that happen before. I've got plenty of clearance and the motor is tied down.

Gary,
A inch of clearance is more than enough for a fan that is not weak or damaged. If the fan was flexing more than a 1/4 inch, there is something wrong with it. I highly doubt the blade are or were flexing over an inch, that seems like an awful lot. Usually they don't put flex fans on a clutch set-up.
You may want to look at your motor mounts or more importantly your tranny mount if it has one. A bad mount maybe allowing your engine to torque from side to side pushing the fan into the radiator on an angle. Just a thought.
