I have the same car and engine as you and I got so tired of trying to get the Rochester 4GC to work consistently. I am also trying to keep my car as stock looking as possible. Here is what I did: I put on an Edelbrock 1406 carb with a Holley/Edelbrock to Rochester 4G 4-Jet Carburetor Adapter Plate, part #1351935 from Speedway Motors. I then got an Edelbrock 1221 14" air cleaner and cut, then flattened the base of that air cleaner. I mated that altered base with my stock air filter housing top piece and everything still looks stock until you look under the air filter housing. I attached a pick to show how I modified the base.
