Street Demon or Edelbrock AVS2 or ?

I've been running a 750 Street Demon on the 360 in my Duster since about 2018 iirc. That engine has a 222/226* @.050" cam which has moderate idle vacuum, I think if I had anything over about 230* I'd run a Holley instead. Edelbrocks and Street Demons are great but they just don't work well with bigger-cammed engines that don't pull much idle vacuum. Mostly the design and lack of tune-ability of the idle circuit, accelerator pump and power enrichment don't lend themselves well to "hotter" engines. I love mine, kind of a pain to do "coarse" jetting adjustments as you have to remove the entire carb and take it apart to get to the jets but once the tune is set where I want it I don't have to touch it throughout the year. Only time I've had to make big changes is when I moved from 5000+ feet elevation in Colorado down to near sea level in Georgia. Back in CO it would start right up and be ready to drive in 2-3 minutes or less even when it was 20 degrees outside and between summer and winter all I'd have to do was tweak the idle mixture and speed just a hair and adjust the choke a bit.

It goes back to the decades-old debate; Edelbrock/Carter carbs are nice for milder street engines as they hold a tune better and are more forgiving but Holleys can be tweaked more to dial them in for higher-performance engines. Doesn't mean Holleys also don't work on mild street engines but they generally aren't as much of a bolt-on-and-go, set-and-forget carburetor.
