I am looking for a new carburetor. I need performance but reliability and decent gas mileage. Right now I get 10mpg on the freeway and my car isn't even that fast. I have a somewhat built engine. I have a Carter AFB comp. series 625cfm carb, edelbrock performer 289 intake, a mild crane cam, and headers. When I stomp on it, sometimes it just lags down, but sometimes it takes of like a rocket. It does pretty good on the freeway... I know that it is flooding and running too rich. I want to get a new carb that won't hurt my performance and will give me a lot better gas mileage. Please give me you suggestions on what would be best. Thanks!
