Swapping 4bbl for the original 2bbl is one of the first and most basic things hot rodders do and yes it will net you more "kick in the pants" don't know how much hp or torque but unless you are racing it's pretty irrelevant anyway. The reason Edelbrock doesn't list a direct swap is becaus most of their carburetors are square bore like the Holleys and the OEM 4bbl setup was a spreadbore design. If you purchase an Edelbrock RPM series manifold to fit your car (which I know they make) you can get a carb to match very easily and any tech you call on for assistance worth their weight should be able to guide you on the exact model numbers. I am assuming you mean you will buys this from a speed shop or from a catalog like Summit or Jegs. At any rate, your 350 which is a small block will really like that change and respond well to it. Keep the carburetor size to 650 cfm or less, you will have good throttle response and get "fair" gas mileage from the setup although I guess that isn't really a concern anyway. I have an Edelbrock on my big block and like it, it is a good streetable carburetor. Many people don't like Edelbrocks, but they are just as numerous as those who do and those who would prefer some othre brand like Barry Grant or Rochester. I would say you will be please with the change over so do it. Oh, about $350 for the carb and maybe $300 for the manifold, just a ball park figure. Used would be cheaper.
