Thanks everyone, I appreciate the help!

It has a Walker radiator with 3 electric fans (2 push, 1 pulls) and gets a little warm at times, since the hood’s side panel have been smoothed I’m assuming the trapped air is adding to it. I also plan on changing the 7lb pressure cap to a 15lb which should help a little too.

The firewall slants back but it’s a tight fit under the hood and not a lot of space for the air to move out. My inner wells are smooth and have no louvers, so I thought adding some vents on each side would help. I can get 5" round polished stainless louvered vent grilles (actual hole size is 4") to dress it up and the louvers should help keep the dirt out.

Panel at the bottom of the grille?, tell me more please.
