Demons are nice looking carbs......umm...and cars too, I guess. lol
I've been an AFB fan since when I had my '65 Mustang. I drove that car all around California with a 625 Carter and it did great on gas mileage. Of course, It was a 302 with a Erson TQ30H cam and I also put a T5 5-speed in that car with a 3.70 year in the 9". The Carter was trouble free and I never had to mess with it. It gave me good throttle response and it was a torquey little 302 to boot.
I think the Carter and Edelbrock options could have been combined though since I believe the Edelbrocks are basically Carters.
