I've always noticed the whistle on '70 Barracudas & Cudas. Never knew what it was caused by, but loved it!

Based on remembered history with a buddies one owner '70, we narrowed it down to the gap between the top of the grille lip and the edge of the upper valence. You know, the panel in front of the hood, and the grille. We used some masking tape to try and seal up an area at a time, and IIRC, that was it. On his, at least. Edit; his was a Barracuda ...

You need to try and hook up with someone that has a wind tunnel. Maybe easier said than done, but that could sort it out pretty quick. Or get some Mopar magazine to do the same since the problem is so prevalent??? Hint. Hint.
Believe me, I've thought the same thing. I would kill for 5 minutes in a tunnel as mine whistles and I am pretty sure it's coming from underneath.
Is "tunnel time" even available.....at what cost?

The top side. I'm not totally happy with it yet.

This is what I did. I taped up the windshield on this convertible, even taped the lower windshield moulding where the wiper arms go thru, plus taped up the moulding on the front of the hood. Test drive up to 40mph...BINGO, no noises. Now the process of elimination began. Off comes the upper w/s moulding tape, no noise. The side w/s moulding tape, 1 at a time...no noise. The lower w/s mldg tape, no noise. The LH headlight bezel...no noise. The RH headligt bezel...no noise. Tore about 12" off the LH side of te hood mldg...it's back. Taped it back up and removed 12" from the rh side of the hood mldg, it's back. Both of these started at 30 mph and left about 40-45 mph. Returned te tape back on the hood corners and removed about 1 1/2 foot in the center of te hood. A new pitch that comes in at 50-60 mph. This mldg actually had a quartet that came in at 30mph and 55 mph. No wonder I was about to go nuts. Now the fix begins. I took the hood mldg off figuring an easy fix. Not so. 70 and 71 Challenger hood mldgs are a crappy fit from the factory as I soon learned. YOu can't adjust them up or down. SO I tried to tighten the gap on what was doable and installed a thin layer of insulation. Finally after bending and rebending for about 30 minutes, the noise is about 90% gone. It will be fine for now until I get time to make another run at it later. The 72-74 should be much easier to adjust because the mounting studs go directly in the front leding edge of te hood. The 70-71 has small wheel opening screws that mount from the under side of the front hood flange. SO you 72-74 owners may want to consider this if you have the same whistle.
This makes sense, I have a crappy aftermarket hood w/ no hood molding and never had a whistle.
