1971 Duster Handeling
Ill add that getting air out from under the hood is a good idea, but I wouldn’t lift the back of the hood. The back edge of the hood is a high-pressure air area, that’s why Cowl induction hoods work so well. You might jam more air under there than you think you’re letting out. Vents in the hood should be up where the low pressure bubble is, pretty much right behind the radiator.
That’s why when jeeps started coming with a 5.9 in 98, there are vents up there.
