Here's a quick review I did on the 625-- New Demon "Street Demon" 625cfm carb
I have not used one of these but if I had to buy a new carb for a mild street car this one would be it. I also love the edelbrock 1406's I've used but this Demon seems to have a more refined design.
I've used holley's too and while they have a LOT more aftermarket support and options they really don't preform as well on a MILD STREET engine. A race engine is a different story.
I never saw the appeal of a quadrajet.
