I love the sound of my Thumpr. People say its not a great cam for performance , but I dyno just under 300 to the wheels with it in my 4.8 and it pulls to like 7300. I would get you a sound clip but for one im in Afghanistan. And 2 LS3CC Has my truck at his shop doing some work for me. Maybe you could talk him into getting a sound clip for you.
