AVS2 compared to Street Demon?

I have also tuned and run Carters and Edelbrocks they are fine carbs just a tad old-school but I HATE the bowl design, can't go around corners or hit the brakes too hard you might stall out!

That's funny I have never had that issue with a Edelbrock but I have had more issues with the holley that I had on my 68 Coronet RT. Never could get it to run right one day perfect next day run like crap. Installed the 800 thunder series all issues went away. There are a couple of guys in our car club that run the street demon and they run ok but a lot more money than the Edelbrocks

You can get Street Demons at most parts stores now alongside the AVS-2 for ~$350. They all work well, I actually like Holleys too. Maybe the newer Edelbrock Thunder carbs are different but I had an older Carter AFB 625 cfm and it worked amazing to be honest, great carb for the street but it liked to boil modern ethanol-gas in hot weather and would spill over a bit from the boosters in hard cornering. It didn't have quite enough airflow for a built 360 so I sold it and got the 750 Street Demon. I think carbs are more prone to have issues due to age or bad build quality vs. design. You might have gotten similar results with a brand new Holley Street Avenger, not saying it's better just that all brand-new carbs tend to run perfectly once tuned unless it's junk from the factory.
