Best bargain sound deadener/ heat shield
Blog is a combination of several posts on 67-72 Chevy Truck forum
If you want to decrease sound you need to go with CCF and MLV. Those stick products are to decrease resonance not block sound.
Here is a great thread on it: http://67-72chevytrucks.com/vboard/s…d.php?t=559596

Here is a good website that explains it all: https://www.sounddeadenershowdown.co…-vehicle-quiet
You can get it all online. The issue is that MLV is heavy. You can get different pounds per square foot but the shipping is what kills you. If you can find it locally you are golden.
Its kinda hard to work the MLV in tighter spots and depending on what you have close to the floor you might have some clearance issues (gas peddle). Ideally you would want it completely connected. I have used it on other people cars and it makes a huge difference.
I used the advice from sounddeadener showdown and I used Noico on my floors for the vibration dampener & ccf
For the mlv I used this product from Home Depot
In terms of sound damping this is some of the best stuff. And a good price. http://store.secondskinaudio.com/b-stock/

Lay the fatmat for sound and rattle insulation. Then use a foam with a foil to reflect heat. I have foam from a generator enclosure on a yacht, it is 1″ thick, with lead shielding, and thick reflective foil. Floor stays cold.
Here’s a quick link I found.
Here’s a source that is mentioned on corvetteforum.com, but I have not compared prices:
