So I got thinking, is there a way to reduce the road noise in one of these amazing cars. I want yo be able to keep unwanted noise out and radio noise in. Any help is greatly appreciated.
Thanks, Andrew

Sound deadener

:iagree: :iagree:

I used the stuff from Eastwood. Made a big difference on the road noise. And I only did the floors and firewall. There is a thread about this somewhere.

Found it.

There is another thread somewhere here about it.  But when I redid the floor pans on my 67 I used "Duct Wrap"
It is the same material that they sell at shows that the name escapes me right now.  Foil on top and stick with a pad to the floor.  Reduced the noise AND particularly the heat enormously. Cost me a little more than $30.00 to do the car.  Pictures here:

Bob, even with half the interior out your car still looks beautiful, what a sweet ride!   :2thumbs:

I looked up the stuff at Lowes and it's just under $19 per pack so you used only 2 packs?
Extraordinary claims require extraordinary evidence.

Hmm, got mine at Home Depot and I seem to recall it was around $13.99.  And I purchased the roll of aluminum tape to cover the seams as you can see in the pics.
I recall 2 rolls did it.  Another member here tried it (from the previous post) and said "couldn't be happier".  As I am.
My wife always brings a water bottle and sets it next to the hump on the floor.  Before, it would be too warm to drink ... now it still stays cool.

I'm using the same stuff but I've only done the firewall before I dropped in the dash.  I'll do the rest of the car when the interior is ready.  It should do a fine job with the heat but I'm skeptical it will make a huge difference on noise.  Density is what deadens noise.  This stuff is pretty much bubble wrap with foil on the sides.  It will help some but if you're looking to cut out a ton of road noise you will need something a little more heavy duty.   :Twocents:

hmm, mine wasn't bubble wrap.  More like Dynamat. It was like a 1/4 inch pad.  Reduced the noise on mine.    :shruggy:

The main thing is making road noise go down. The car i will be putting it into is a 72 Charger SE that at the moment doesnt have a motor, so im putting the 318 from my (non restorable) 71 Charger into it. The guy i bought it from put cherry bombs on the exhaust and it makes everything really loud in the car. Granted I am only 17 and could deal with it but i plan on putting a nice sound system into it and id rather be able to hear people talk or the radio in it then just the noise from the pipes. Thanks for all the help I think i might just go with the Duct Wrap, So far thats the cheapest and it seems to work quite well.

Reducing noise is a multi-pronged effort.
Squeaks produce noise. Rattles produce noise, so does the wind, the exhaust system, the tires, a worn set of axle bearings, fragged diff gears, etc.
In February I welded in frame connectors and torque boxes. I expected an improvement in the stiffness of the car, but what REALLY got me was how SOLID the car felt afterward. Most rattles are gone. The car soaks up road dips and bumps like a newer car.
Two areas that many people forget: Insulating the speaker deck/package tray, AND the divider panel between the rear seat and trunk. Most people know about Dynamat and Hushmat. Some guys install the stuff to the underside of the roof before installing the headliner.

My car has absolutely no road noise.  And that's because I refuse to wear my hearing aid while I'm driving it!!  :smilielol: :smilielol: :smilielol:

That made my day. I was thinking of putting it on the roof before the headliner, but does it help?

LOL!   :smilielol:   So how do you hear the cop when he pulls you over for going 110 in a 55??
"not sure what you're saying officer, but hold my beer and I'll find my license"   LOL! :D

Seriously, the only noise I have is the exhaust. And I like that.

I'd be a bit concerned about condensation causing rust under the lining just like you get under the vinyl top and under the trunk mat.  :Twocents:

I am thinking that spraying Lizard skin then gluing Jute padding to the underside of the roof would be the way to go.  My thinking is the Lizard skin will insulate both sound and heat as will the jute, and the jute will collect and dissipate any moisture that may form, just thunking  :scratchchin:

First the stuff I used sticks to the floor.  The foil like properties made it conform to just about everything.
If you install it securely, I would think that is minimal.
And the carpet was snug, yes -  but being only .25" or less, it was quite usable.
