Holley Street Avenger 770 for 408?

I have a 408ci running well with the Mighty Demon 650 but want electric choke. I don't like tuning carburetors, I'm at the point where I just want to drive it and not sit with my foot on the pedal for 10+ minutes to warm it up.

I've heard negative about Street Avengers in the past. What are thier drawbacks?

Duster, Edelbrock heads, 4 speed, 3.23 rear.
