Since you don't have the original engine and the current one runs ok, why not leave the 4 Bl carb and manifold. Otherwise you have to find a 2 Bl manifold, carb and air cleaner. You might look for a 57-58 passenger car 4 bl air cleaner. They are fairly expensive as the the guys doing a correct restoration want them. Most people that look under the hood don't know what was stock anyway. Fred
