It's a Carter AVS 4966S. I haven't touched any of the internals, including the springs. If nobody previously changed the primary jetting, it has .089 primaries with .066/.063/.058 metering rods. I'm not sure if Edelbrock springs work with the long AVS metering rods or if I'd need to convert to Edelbrock jets and rods (and use flat covers) first.
