Opinions on my grill block plans, please? (pics inside)

Here is the front end of my truck as it is currently:



This is what I had planned to do (imagine the black is tape or some
other material):




In your experience will that leave enough cool air coming in for an
everyday driver (no towing and only hauling relatively light loads)?
thanks,
-Tim


Edit: I don't know why the pictures were different sizes.

With the massive fan on the front of that motor, I'm sure that will leave plenty enough air flow for the radiator.

I've mentioned it elsewhere, but I should mention in this thread that I've
removed the mechanical clutch fan and have installed a single 16"
electric fan that is thermostatically controlled. I got a good one and it
moves a lot of air, but I'm hoping it won't have to come on very often in
my mostly highway commute.

Start with blocking the upper opening, and seal the hood gap with the squishy foam gasket from the home center. Then I'd try blocking the middle opening, as well. If possible, I'd run it with just the lowest opening unblocked. By deflecting as much air as possible up and over the (relatively) smooth body; and prevent as much air as possible from going under the truck; which is much rougher.

Is there a gap between the spoiler and the bottom edge of the radiator? If so, you can block it off which forces all the air coming into the grill to go through the radiator. It may well be open because there is way too much air coming through the three grill openings. You can "tune" things to leat only as much air in through the grill as needed, but then "use" all of that air to cool the radiator.

By having the air intake near or just below the stagnant point is the most efficient, I think.

The Ultra-Gauge is currently a better value and gives you more gauges to see at one time.
