I had a friend years ago that had a '72 nova.. no carpet no insulation.. a built 350 and a rebuilt M-22 4 speed.... you couldn't cary on a conversation at a normal voice level.
Insulation plays a very important role in sound deadening.

The Fat Mat I used works better than Dynamat in my opinion because its the same but 1/3 the cost. I saw Darrin Tosh use it and tried it myself. A double layer on everything but the roof was all I needed. Can't remove the head liner in a crewcab alone or with friends. It will end up damaged. The front windshield needs to be removed for it to be safely removed and installed.
