I really like the QJet on the stock intake. You won't notice any difference with an intake/carb replacement in anyway. It isn't enough of a gain in HP or loss in weight. Better to spend the money saved on the intake and putting it into the carb. The Qjet is a very good carburetor when it is setup correctly. Not that there isn't anything wrong with the Edelbrock. It is also a tried and true AFB style carburetor. I would have Cliff rebuild it. You will really like the way the car responds when the carb it setup for your car. After the rebuild, you should be good for years of enjoyment.
