The Street Demons have modern features and tunes that the tired old CarterBrocks don't. The only guys that still prefer those old carbs are the ones with no experience with the Street Demons.
Check for refurbished models on ebag.
Some information on the Street Demons:
'I haven't had any time with the new AVS yet. We sell them at work. Looks nice. What I have done is swap an Edelbrock 625 AFB for a 625 Street Demon. I found the SD on Ebay needing some small repairs and a kit cheap so I got it. So far, it's been a pretty big improvement over the Edelbrock.......not that the Edelbrock was a poor runner. Just the contrary. With the SD though, the idle is smoother, the mileage picked up, but where it really shines is the transition into the secondary barrel. It's very smooth yet very noticeable at the same time. It goes right into the secondary circuit smoothly, but you dang well know when that thing opens. It sounds good too. lol' www.forabodiesonly.com/mopar/threads/avs2-compared-to-street-demon.427541www.youtube.com/watch?v=DPOuEOkazVcwww.speed-talk.com/forum/viewtopic.php?t=38709www.youtube.com/watch?v=YNAlVFtUFL4There is lots more information as well as tests out there.
