Anyone Running a cowl induction Hood on a 73 Duster

Before I disagree with you, let me agree with you. I've seen a few really fast cars, that are up here. So you're probably dead to rights on your statement.
That said , it's time for "un-ding", ( is that how I spelled it before. In my experience ( and I'm probably wrong.) I used to live in Monroe twp N.J. right down the street from Englishtown. I had a 496 RB in a 1973 challenger with a steel shaker hood, complete with factory seals, sweet looking but totally useless. The little helicopter seems that fall from maples would fall through the grilled openings, I could drive 10 miles, and they will have hardly budged. I had a 1969 Barracuda with a fiberglass 6 pk hood, went from 69 front /78 rear jets, to 71 front/78 rear jets, it seemed to effect the engine, hacked it off, and replaced it with a super stock hemi hood scoop. That seemed even more effective.73 front/78 rear. At this point it should have been a pig, but I managed 17.5 mpg. Still it smelled like gas at idle. If your speed is over 140 mph you need a NASA scientist, but if you need a hood scoop for your skyscraper intake, choose something you're going to like for a long time, cause you'll be stuck with it?

The The cowl hood is a good choice on most cars that do not have a modified engine compartment.

The engine compartment on uni-body cars are sealed. Years back we would lift the rear of the hood to let the air out that flows through the grille.

Most fast full grill cars will run a cowl hood for this reason. Cutting out the fender wells also helps if you run a scooped hood on a naturally aspirated car. Seal the scoop to create forced induction and cut the wells out to reduce lift.

A-bodies really get lift on the big end if you have the power to get the speed. Letting the air out from under the hood any way you can helps.

So with this said. Choose a scoop for what you are building. Will it be used to grab air. Or will it be used to relieve pressure. If its for looks? Do what ever you like
