No matter what you add, the Pantera will not quiet down like a Lincoln. There are industrial-strength explosions going on inches behind your ears. One owner with a gear drive cam wears earplugs or ear buds. Another with straight-cut gears in a blower does the same to kill the whine & exhaust note.
If you glue anything on the engine side of the firewall door, be sure the front main seal isn't leaking or you'll have a sloppy mess every time you pull the access door. There will be no place you can set it down without oiling a surface. And in places on a stock setup the pulleys get pretty close to the metal door so the pulleys may cut their own clearance and again make a mess of any insulation. Relocating accessories makes things easier. I'd also suggest high-temp adhesive if you glue anything; the whole engine compartment gets pretty warm when driving any distance.
If I wanted a Lincoln I'd buy a Lincoln. There are ways to deaden the sound but the insulation is more for keeping the heat out of the cabin.
One thing that can be done is make the engine access door out of more significant material.
I made mine out of 3/4" plywood. It deadens the engine quite a bit.
The other thing you can do is use a rotary A/C compressor and don't add foolish things to the engine like gear drive timing sets.
By comparison the Pantera is very quite compared to the GT40. There is a part of this clip where you get an idea of the noise in the cabin.

I turn up the sound on this. Only a GT40 sounds like this.
