AVS2 compared to Street Demon?

Hey, thanks for that write up! I am going to be using an 85 360 truck Quadra-Jet, chokeless with a milled airhorn, someday. I’ll have to double check but it has something a lot like an annular primary booster. Still just got the two big fuel dump tubes in the rear. It’s a warm weather only driver, so a choke isn’t too big of an issue. A little extra air door spring tension to prevent “Quadra Bog”. I’ll have gear in first, at least 3.90, maybe deeper. If I don’t like the way it works out, I’ll go with a new AVS, one of the 650 cfm.
