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.

Erson doesn't seem to have any bbc retro rollers in stock. I entered both the part # and then the grind # on their website and get the message that there is no such part.
How the heck do you buy cams that don't exist ?? LOL.
Well, duh, just saw you wrote it is not in their online catalog...

This is the exact spec. I have been setting up my BBC distributors for 55 years, with full mechanical advance at 2,500.

Great work!! I love a Chateau Slate '66! - Bill W
