Well, I apologize for chumming the water then fishing .
I very much believe exhaust, cam and compression play a huge part.

That chassis dyno video clip is my car from about 20 years ago.
LT1, Heads ,Cam , Compression , Tri Ys

What it does share with my LS7 is the same exhaust.
3 inch X , headpipes, Walker 17770s 3 inch tail pipes.
It didnt sound a lot different than it does now.
