There is no replacement for the carb in your car. You have a spread bore, the replaces are not and are less CFM.

As curt86iroc stated, you can change to large lmetering rods, you can also change to a Float pin and housing from a truck which has larger opening which will allow more fuek flow into the carb.

Years ago in earky 90s GM offered a carb and ECM upgade so you could use a 350 motor, but I don't know if they offer it.

I installed a 355 in my 84Z, and after allot of work I never got the carb to work well so I dump the set-up.
