Dave,
I see a bunch of things on the car I can let you know about if you want to pm me. It's a 250hp 327 with the fuel bowl added. The SS wheel covers were obviously added, but it did come originally with white walls and the full accessory wheel covers. The diagonal braces inside the quarters were typical of BOP cars, especially Willimgton cars, as yours is. The engine pad stamp photo is blurry but I'd guess it ends with an "S".
Congrats on the purchase. It doesn't need much to make it more correct and you'll have a great driver!
