Will this this radiator block make any difference of aerodynamic drag? A little bit? Just curious?

I have also started plugging in my block heater at night. It runs just over 500 watts, so it's kinda wasting electricity if I run it all night. I am planning on setting it on a timer, but am still looking around for it. I have one here somewhere....
It is not good to completely block airflow to the radiator, melting or not. Yes you can make a block that is 100% radiator sized, but it still needs to be some distance away from the radiator. SOME air movement is necessary.

You've been around here for some time right? Aero drag reduction from that kind of block will be too tiny to detect. And heaters have been discussed too, with optimal plug-in times for one example running just over an hour.
