fan blade destroyed the radiator

I had my first bad day with my car. I jumped on it off the line in 1st and 2nd and then the weird engine noises began. I shut it off and coasted to the side of the road. A little smoke from under the hood and coolant everywhere.

It seems one of the fan blades came in contact with the radiator and put a hole in it.

When I put A/C on this engine, space was at a premium. I found the water pump on a 302 isn't the same as a water pump on a 289. The oem fan spacer was too long. I couldn't install the fan to the upper pulley. I used the thinnest spacer that allowed the fan to clear the crank pulley. It resulted in a 1/2 gap between the fan blades and the radiator. I thought it was too close. The only way I can get more clearance is to install a thinner radiator.

The current aluminum radiator is a 2 pass unit, 20 1/4 tall x 18 3/8 wide. The core is 2 3/8 inches thick. Is it possible that a thinner core with more passes would have the same cooling performance?

Is it normal for a fan to flex like this? (it's a 50+ year old Ford Oem 6 blade used for 289's with A/C.)

Thanks
