Have you seen Shawn Maher's 46' http://www.stovebolt.com/gallery/maher_shawn_1946.html

I have upgraded my 51' to a 78' c30 frame with a 454 big block. There are lots of pictures in gallery that can give you lots of ideas. Hope you find what you are looking for. I have spent hours just looking at all the cool rides in the gallery and the search option in the forums has helped out alot. Enjoy the site.
