New Street Demon carbs

I've heard a majority of good things about the Street Demon in my recent research. Nothing is ever perfect and there are a lot of ham handed users out there there so the very few neutral or slightly negative reviews I found was a big plus for it. That said, I ended up buying a 650 AVS2 which I just got running this weekend. The car idles and runs significantly better than with the Holley it replaces. I'm pretty sure the SD would have given the same results and it was pretty much a toss up. I think the Edelbrock tuning kit is a little less expensive and the SD can be picky about the height of the air cleaner base were a couple of points that may have swayed my decision.
