I am wondering if it is possible to have this clean front without having cooling issues. Some ideas that i have thought of are to install an oversized radiator, or possible relocate the stock one so it would be further forward, in the custom bumper, with a small hole on the outside, but that would defeat the purpose of having a super clean and smooth front end.
Any ideas on how to make the aero improvement while remaining safe and cool?
Thanks!
I have a drawing that i can post if it would help but i don't have anything physical yet because i want to make sure the concept would work before i start the build.

I have done a lot of testing of grill blocks and custom bumpers, and have found that it is very difficult to improve on what the original engineers have done. When I decrease air flow to the radiator, the cooling fans are able to maintain the coolant temp at an acceptable average temperature, but there is more to it than that. When I watch the PIDs, I can see the temperature cycling up and down by 10 or 15 degrees F, in two minutes or less, and this cyclic temp change can be hard on your engine. Your temp gauge may indicate that the temp is fine, but you won't be able to watch the cyclic temp change.
When you watch the temp via a fast PID, you can see that your engine maintains a very steady temp, give or take about 2 or 3 degrees F, but when you start changing air flow through the radiator, you can create a new problem.
