Yes, i did go with the Turbo Mufflers. A couple of thoughts on sound just based on experience. Alot of initial advance seems to provide a more throaty sound, retarding softens it some. Even the idle mixture not being in the mid 13s to low 14s air fuel ratio will have an effect. I recurve all my distributors. Most BBC love around 15-20 initial advance with the mechaninal limit at 36-38 degrees(this is all without talking about vac advance) Im pretty consistent with all my builds at 18 initial and 36-38 max. So when you hear the car idling its around 18 with just a few more degrees of vac advance on top of that. If you wanna know more just ask. I love doing all this detailed setup work to make them run just right.
