I'm not aware of a direct bolt on aftermarket 2-barrel. If your new to carburetors I'd suggest you look into the Holley Street Avenger 4-barrel, they seem to be more user friendly.
Pick up a good intake & air cleaner, be prepared to have to work out the throttle connections & tranny kickdown. Nothing I've seen is a direct bolt on.
Hopefully someone here that's done the swap will chime in to help in the process.
