Have you read up any on the Street Demon and how it works? I think one of the things that impressed me was the tunability of the spring loaded air door for the secondary goggle valve...
Exactly. Like the TQ and the Qjet. Just understand that to take the bog out (and you should tune it so there isn't a bog...some dudes like the big VaaaHaaaaaWhaaaa when the secondaries are opened and the air valve flies open like a screen door...if your lucky when we get cheeseburgers I'll tell you why years ago I stopped tuning TQ/Qjet carbs...it's a regular deal) you may never get the air valve all the way open. Some guys think that's ok, but I'm not one of them.
Same for the 1850/3310 Holley carbs. Most of the time, the secondaries never open all the way. And I hate that.
Like I've said before...brass and drill bits are cheap. It's much easier to configure a Holley style carb.
