Engine Mounting

What are my options for mounts to put a 383 in a 64 Dart. I don't want to do a motor plate. I've seen BB in an early A body before but don't remember what was used. And what exhaust manifolds/ headers might work. Would consider fender well headers. I was thinking of doing coil overs and remove the T bars. That would extra clearance under the car. Any info would be great.
