Which carb would you get?

I had a 3310 on my duster and like you was having some problems with it. I replaced it with an almost new (ebay) 750 mech secondary 4779. Like it a lot more. I'm sure that gas milage is down, but that wasn't ever much of a concern. I always liked the carter avs carbs i had on old musclecars. Next carb I buy might be an Edelbrock thunder series avs. Who knows?
