Cooling question for experts

[Action]

After seeing some pics on here, I gots to thinkin.

If someone installs a snout but doesn't use the pieces behind it to seal off the large openings...will engine cooling be affected much from airflow being less through the cooling stack? It seems like a lot of air coming in through the grill could just blow around and over the stack.

Possible...but you still have your splash shield rubber to keep the air from rushing out the sides.
an ECV radiator is just longer. And if your extended nose is done with the correct side metal shields for hood lighting, that will also help. But I doubt anyone is going to that extent.

i have this conversion and noticed no difference.

There is a huge gap behind the headlights.
