.... The fire-wall vents would be put in place to allow air going through the radiator to escape the vehicle, narrow hoods can be a bit claustrophobic ...
you have a belly pan under that truck? how do you think the air that comes in the front opening gets out of any later vehicle that doesn't have the hood side louvers you have??? early rodders didn't leave off the hood sides for better engine cooling, they did it so you could see how cool the driver was
