The answer to your question is no.
A large part of what made the old muscle cars sound as good as they did was the crank angle in the V8 engines. By "crank angle" I mean the crank's rotation angle at which each firing happens.
There is another definition of "crank angle", being the angle at which the cylinder fires relative to TDC, but that isn't the one I'm referring to.
Your induction system is also dramatically different from the old way. Some years back I made some changes to my own induction system, making it a bespoke ram air system, and to my pleasant surprise it changed the sound of my engine. It sounds a bit like an old MGB now. I like it.
In short, there are technical reasons why your V6 cannot sound like the old muscle cars.
A neighbor of mine has two vehicles with V6 engines. He put "glass packs" on both. The make the cars sound like junkers that need new mufflers.
