Sonic I just got a brand new factory one. If you can wait a day or so I will measure it for you and even take a picture of it!

Just a sound pad question. Anybody have an idea how much noise the factory sound pad actually eliminates? Or, what would be a better material - something like Dynamat? I haven't found anything sofar that seems to do a decent job. Sound pads are easy to make. The last one I made was from sound proofing material with foam, aluminized mylar and a thin lead(?) layer in the middle about 1 inch thick. I'm thinking of trying to find something else when I get to that point with my '69.

From what Ive read in this forum, the new OEM sound pad is pretty good...better than the original pad and lighter weight.

I can not speak from experience though. I am using a light weight 1/2" thick material called 'Thermoshield' that I bought for $20 a roll at Pep Boys. It has a shiny foil heat reflective surface, and a cloth-type material underneath. It is easy to cut and work with.

I lined the inside of the carpet last week with two layers, and tonight I installed one layer in the engine compartment, using the 3M 90 adhesive. Each layer reduces the sound about 10% or so, so Im at about 30% reduction from the original sound (my car had no sound pad originally and was very loud). I am going to do one more layer in the engine compartment and then tape down the outer edges of the material with high quality duck tape.

Primarily, the high frequency air intake scream is what is being reduced. The low rumble is reduced to a lesser extent. Thats OK, I like the low rumble.

My car had dynamat installed on the firewall behind the rear seat. It does nothing to reduce engine noise as far as I can tell.

Hello

How you managed to install the new sound pad with dropping the engine, can you share the trick ?

Thanks
