Fan too close to radiator?

67 Barracuda, 273, non A/C stock radiator. It's way hot here, and I'd like to move more air, so I want to move to a 340 7 blade fan. I mounted it up and it's .6 inches from the radiator. Is it too close? Not sure how much the engine mounts flex. I can always get a shorter spacer, but I'm not sure it's necessary..
